Testing Screwed up Abstract Algebra exam unsure if I have the ability to do math.

  1. Sep 22, 2012 #1
    After getting back a result in an Abstract Algebra exam (In which I only got 70%), a result just below the class average I am having extreme doubts about my ability to become a mathematician.
    The real shock was that I believed I understood the material well enough to get at least 90%. I am aware of where I went wrong in the exam, and understand my mistakes, but there is a lingering doubt now (Due to how well my classmates did) that I have subpar mathematical ability, and should consider leaving the subject. This causes me a great deal of distress as there is nothing else I can consider doing, and It was and I think, still is my dream to become a mathematician. Furthermore this exam result will probably leave me with a B in the subject when I had hoped for an A+, which in turn has ruined my chances at a top grad school.

    In hindsight I realise I did not put in enough time revising certain areas before the exam, but I do not believe any of my classmates put in a great deal more effort than I did, and yet they have recieved vastly better results with minimal effort. The ease at which some of them seem to pick up the concepts which I have to bang my head against a wall for is truly frustrating and I cannot believe this is anything other than an indication of a lack of ability in pure mathematics.
    Is it possible to come back from this and contribute something to pure mathematics or should I start considering a different career?

    I do not have the experience to directly answer your question, but if you know what you did wrong and that your preparation for the exam was not adequate, perhaps if you correct these sorts of deficiencies you would be fine. You say you do not believe that your peers put in as much effort as you, despite your lack of preparation, but how do you know? Does it really matter what your classmates are doing? Perhaps they have a better foundation and you just have to play a little catch up (I do not know you, this is just a suggestion). Have you tried talking with your professor to fix the problems and see if you can turn your grade around? Perhaps some of your professors could better answer the question regarding your ability.

    As well, I don't know what your other grades are like, but I doubt having one B is a for sure bar to gaining entrance into a great grad school... nor would having straight A's guarantee your admission.

    I am sure if I spoke to my professor in regard to my ability/talent he would advise me not to become a mathematician.
    I don't think it is just that I am a poor test taker, I think this may be the final blow in my quest to become a pure mathematician. Who has ever heard of a mathematician getting below average in a math exam?

    You seem to think that success in mathematics or in grad school has something to do with natural ability. It's not really true. Way more important is being able to work hard and to love the subject. If the other students put in a minimal effort and don't work hard, then they won't succeed in grad school.
    If you can get an A+ by putting in the work, then go do the work. Working hard and persisting is way more important in grad school than understanding everything immediately.

    That is what some people say, then there are others (Paul Halmos for instance in his biography) who would tell decent students but not brilliant ones not to go into mathematics.

    If it were not natural talent, then the only other things I can think of possibly causing problems are:
    1. Not taking notes in class (I just reread the textbook if I have to remember something)
    2. Not doing extra problems. I have not really had the time to do this with many other subjects also requiring me to submit weekly homework.

    I'm in physics, not math, but here's something that is relevant:

    take notes no matter what.

    its not for the formulas. its because the professor might solve an EXACT problem that's unsolvable in any other way except by already knowing the solution.

    DUDE! Don't worry. I got like a 55 on my first undergrad algebra test. I don't remember the average, but it was much higher than that. I still remember the 20 point problem that really screwed me: If a^2=a for all a in G, prove G is abelian.

    I'm now in grad school,. So don't sweat it.

    Natural ability:
    DNE! Anybody who's good has worked hard at some point. There are probably genetic variations in maximum ability, but I highly doubt a few tests truly represent ability to be good at math.

    Think about it, if this were true, African Americans and women of any race would, on the average, have a lower natural ability than white men, which I doubt very, very strongly; they get less practice, encouragement, and might not grow up in an environment in which mathematics and science are interesting enough to warrant any attention.

    Getting into a top grad school:
    You can have perfect grades and not get into a top grad school, and you can have imperfect grades and get into a top grad school. Who cares about top grad schools anyways? Do they have magical powers to make you a better mathematician? If all you care about is doing mathematics, does it matter if you're doing it at Bob's Bible College or Harvard? Even if you do go to Harvard, if math is anything like physics, you'll probably still not become a professor, by virtue of the academic market.

    Getting hit on the head is a good thing. It happens to everybody some time or another. Now you have to double down, and work twice as hard... I highly doubt a 70% will prevent you from getting a B+, A-, or A; the professor has designed an awful course if you're not allowed to mess up an exam (which is a frequent occurence) and still get a good grade in the course.

    Also, this guy is always inspiring:

    it would take some arrogance to assume your are a brilliant mathematician by default (if you were getting excellent grades). you have indicated that you are not taking notes, having difficulty with the material, and perhaps also you are assuming understanding by passive reading. these are easily correctable: realise when you're behind in the material and push those extra hours needed to attainment. the office hours are there to be used by the student to ask questions.

    It's true that I smoked everything in all my theoretical math classes in my undergrad, but I got below average grades on many exams in lower level classes. Of course, I am not going to make it as a mathematician, but I think I will finish my PhD this year.

    I feel like a complete idiot now, after having so much trouble writing my thesis and not always being on top of things in graduate level math classes. If it were only a matter of being an incompetent mathematician, maybe I would stupidly persist in it. But the real issue is that, on the research side, I am not motivated in the slightest by trying to compete in some kind of publishing game, doing "original" work for the sake of doing original work. I am only interested in somewhat selfishly pursuing my own understanding of math and physics, not what other people think is interesting and what are the "hot" topics. I always took it for granted that there would be a place for that in the mathematical community, but I was wrong. I am completely unable to guarantee any publications within a few years, if I am to pursue my true interests. The only possible way to succeed would be to pursue research that I am not motivated to do, and with no motivation, I can't overcome the difficulties that research presents.

    In the current state of affairs, I don't know that I would tell ANYONE to go into math, unless they have an insane compulsion to do it. The only people I would tell to go into math are the ones who are far enough ahead of the game they don't even need my advice on the matter, so I would say to anyone wishing to go into math, "don't say I didn't warn you." I'm not sure if "brilliance" is the right criteria, but I agree with the notion that it's not a good choice for most people, including most people who THINK it is a good choice for them (90% of math PhDs don't do any more original research after the PhD). I was pretty into math, but I am so burnt out now, it's not even funny. If you are into teaching, it's okay, but if you want to do it for research, I don't know if you have to be brilliant, but I think you at least have to be either way ahead of the game or you just have to have the right personality to fit into the mathematical research community, which means you are really good at cranking out papers as fast as possible, above all else. There is no time for the laid back philosophical musings and reflection on math that has been done already that people like me would like to indulge in, and I'm not alone in this. My friend who is about to defend his dissertation in PDEs said people just quote a lot of results that they don't understand and he felt pressured to rush through reading papers, instead of taking time to understand them. The ones who survive are not really the strongest, but the ones who are the best adapted to working in this kind of high pressure environment. Much like natural selection.

    Most people should realize that they are likely to be destined for a teaching-oriented job, and therefore, interest in teaching is equally important to interest in math. For teaching-oriented people, a math PhD isn't quite as bad of a deal. All you have to do is make it through, then, you can go and focus on teaching.

    A quick question, how hard did you have to work to "smoke" the upper level math courses? Or was it for the most part just natural?
    Also what do you plan to do after your Phd?

    Well hard work vs natural is a very prevalent false dichotomy. I would say it was pretty natural, but a lot of that had to do with smart work, rather than hard work. A professor at my undergrad said I was brilliant at my graduation, but secretly, I knew I was CONSCIOUSLY DOING (as opposed to my brain doing them for me, as many uninformed people would presuppose) a lot of things that no one else would have even thought to do, such as carefully spaced review, and constantly mulling things over in my mind in just the right way, so that I always had every theorem and even its proof at my finger-tips. In grad school, the pace was too fast and my old methods failed to keep up. It was not possible to be so thorough. So, I didn't stand out in grad school, anymore. I made it to become a doctoral candidate, but not in the most impressive way. I may have some genetic gifts, but it's always been my experience in everything I am good at that it's not just how hard you work or how good your genes are--a lot of it is how smart you work. That's sort of the moral of my life, I think, and it annoys me to no end that most people seem completely oblivious to the whole idea. You can play chess all day and improve only a little bit. But if you don't use such a stupid strategy and actually try to learn what to look for, not just blindly practice, then you improve. Two people with equal ability can put in the same work and get drastically different results because one knows that tricks of the trade, and the tricks of learning in general, and the other is blindly try to practice it in any old random way, hoping to get better.



    Basically, abandon the field I worked so hard to learn, except maybe in my spare time. Engineering, insurance, operations research, whatever I can find.

    You had a professor exclaim at your brilliance? That makes me quite envious. Why would you give up on mathematics? Why not just work on some less interesting mathematics for a while to secure tenure and then win a fields medal or something?

    Also how easily did you remember the proofs of certain theorems? I find myself unable to remember certain proofs especially the intricacies involved (Despite thinking about them for a long time in a conceptual manner). The ease at which some mathematicans can come up with original proofs whilst reading a text is startling to me and I am unable to replicate this.

    My undergrad profs were wrong. I never interpreted them as saying that I was destined to be a Fields medalist, just that I could have a successful career in math, if I worked hard. But they were wrong, even with that interpretation. I turned out to be terrible at math research. No good at all. Barely even capable of finishing my PhD, if that. Plus, I just don't think it's a very compelling or useful thing to do. I look at what engineers or physicists do, and I am jealous. I am proving some theorem that no one cares about. They are building cool robots, medical technology to improve people's lives, 3-D printing, all kinds of awesome things that have to do with real life. Genuine contributions to society. It's very easy to argue that math might be useful eventually because it's very hard to predict applications. However, you could argue that any kind of research COULD be useful. Like researching the best way to pick your nose. How can you predict that something useful won't come out of it? That may be an extreme example, but the point is that all research is not equal. I think things should be geared more towards applied stuff. Not that pure math shouldn't be studied, but there's way too much emphasis on it, and there ought to be more of a link to the applied stuff. Even "applied" math isn't really applied enough, a lot of times. Part of the problem is that the body of knowledge is now so large that it has become unmanageable and people are forced to specialize too much.

    Math research is HARD. If you aren't motivated and don't really believe in what you are doing, it's just going to be completely miserable. I am already very burnt out doing that from grad school.



    Retention is just a matter of reviewing and making things memorable. Review after one minute, one hour, one day, one week, one month, one year or some such thing. I used to review the contents of my electromag class in my mind every day, going through all the important points in the material up to the current material.

    @OP: One poor test isn't indicative of anything except that you did poorly on one test. If you have a pattern of low scores, or significant gaps in comprehension, then you may want to consider reevaluating your goals.

    It is very important that you get a handle on that kind of reaction. As long as you understand what you did wrong--and not in a general, abstract way, but in a very specific, detailed way--then you are moving in the right direction. The most important thing is not that you failed the test, but what you are going to do about it. Wring your hands and despair? Or dust yourself off and pummel those books until you can do that test in your sleep?

    When you get a bad grade--and believe me, this won't be the last--give yourself a set amount of time to mope. 12-24 hours is good, so long as you have at least a night to sleep on it. Then take hold of yourself, tell the whiny, emotional, self-pitying part of you to get back in its box, and figure out how to improve so you don't make those mistakes again.

    I don't know how to ask this without sounding accusatory, so I'll have to settle for assuring you that isn't my intention or tone. I'm just genuinely curious:

    Wasn't that something you were aware of prior to going to grad school? I mean, for some people the fact that math isn't a "practical" field is part of the allure, or at least something they acknowledge before pursuing it as a study.

    Was it something you were aware of beforehand, but only came to find objectionable later on?

    I really wanted to do mathematical physics, which is not really practical, but is directly related to reality. But, the closest I could find as far as advisers to what I wanted was a topologist. He pulled me more in a pure math direction, but that was never really my intention. I wasn't really aware of how pure math it was going to be. I thought I could be more on the physics side than it turned out. Plus, back when I went to grad school, I still thought string theory was a promising approach, but it has been clearer now that it is probably not, though I don't want to make any definitive statements about it, since I don't know that much about it. The failure of string theory changes the situation quite a bit in this neck of the mathematical woods.

    That is very unfortunate. I'm sorry that your studies were not what you had hoped. Thanks for indulging my curiosity.

    I have seriously been considering leaving mathematics over the last few days.

    Things I have been considering:
    1. I do not seem to enjoy "doing" mathematics as much as I should, rather I enjoy thinking about what it would be like to be a pure mathematician of the caliber of say Gauss or Euler, I seem to have romantic notions of mathematics.
    2. I have no idea what else to do with myself, engineering does not really appeal to me, and neither does going into say academic physics rather than mathematics. The class I am enjoying most at the moment is a philosophy course, but I don't intend to become a useless philosopher. I seem to enjoy asking deep questions, but most of the mathematics I see and or do does not really have me doing this.

    Are these signs I should just find something else to do?

    Knowing me, I would probably support such a decision, but it shouldn't be based on one test score. A single test score is irrelevant. If it is the catalyst to make you realize you don't want to do it for other reasons, that's a different story. In my case, my thesis went too slowly and there were several mishaps, which made me doubt my abilities. However, maybe I just got intimidated too much by grad school. And maybe it's just hard and takes a lot of work. So, it isn't so much that I doubt my abilities. The real issue is I realized this isn't what I want to be doing. Temporary lack of success was just the catalyst that made me realize it.

    Also, I think math can be a great second major if you don't mind spending the extra time or money for that.


    It may be that you are actively looking for reasons to do something else, so you are biasing your decision. But that in itself is a sign that maybe it isn't what you want to do. Or it may just be temporary discouragement. In my case, I really don't care if my decision is biased--I just want out, no matter what. If I could have been an academic mathematician, that has been ruined, now. But actually, I am happy about not being an academic mathematician.

    Deep questions. Hmm. There may be various different standards for what "deep" is. "Deep" to mathematicians might mean "difficult" or something requiring lots of background knowledge to understand. It might not mean something that anyone cares about, outside the math bubble. Group theory is kind of deep to me because it's secretly not really about a gadget that has a binary operation on it with associativity, identity, and inverse. To me, it's really about symmetry. All kinds of symmetry. Of course, there is the more nitty-gritty technical side of it, where you do things like classify all the groups of order 85 ad so on. A lot of things don't seem deep because the mathematical community has huge issues with providing the motivation for stuff right now. To the people who would tell me you just have to do the problems, the issue is that that they didn't put it in the problems. If you want to motivate it by problems, that's certainly an option, but I don't see it. I just see problems that teach you how to use it, not where it comes from.

    I don't know that there's a profession that deals solely with "deep" stuff, though. There's always the nitty-gritty technical side, too.
