I have a passion for pretty much all scientific subjects and I gladly spend all day accumulating knowledge relating to it but I still find the exams in university pretty hard. I wonder how people that don't have a passion for these subjects manage to pass tests. I can't just go to lectures and read notes if I do that I don't understand anything what I have to do is approach the concepts from all different angles until I truly understand it, and this requires learning all sorts of stuff not covered by the course and I like doing this but it takes time. At night I usually spend 1 or 2 hours thinking before I fall asleep so I like to contemplate the concepts I've learned and I always uncover new information this way and you'd think some that does all this would find exams easy in college but thats not the case at all.
The trick I've found is I just get a load of past exam papers and I practice them then when I take the test its a joke. Got 100% on my last physics test that way. Do you think its better to keep learning and college separate meaning for college you just learn how to pass the tests but for actual learning you do your own thing?

I posted this on another thread, but I think you will find the link useful. Practice is how you learn. "You don't know physics unless you can do the problems." (Freedman) This concept is true, so keep practicing from old exams and try do do as many exercises as you can. You learn by doing, it helped me in algebra 1 and still helps in calculus 2. It helped me in physics as well. I'm currently self studying physics; doing the problems, *learning from your mistakes* is where the true learning comes from.

Styles of learningTRY TO GO FOR "THE ZEITGEIST MOVEMENT " AND "THE VENUS PROJECT" ON NET . I THINK YOU WILL LIKE IT.IF YOU DO LET ME know , am there too........

The deal is that once the understanding is there the problems gets trivial, in my opinion doing problems should just be used as a way to see if you understand the material.

for all intents and purposes, physics is a discipline of math. You could understand conceptually how something works, but if you can't work it out yourself mathematically, what good is it? This is the reason I have gone into physics. I read so many lay persons' physics books, and understood concepts.. but then I had a big "now what?" moment. Without knowing the math well... how could I build anything off of that. I'm not sure how anyone could think that understanding and doing the problems out is not important..

I didn't say that the maths wasn't important, I'd say that you don't fully understand the physics if you don't understand the maths. But what do this have to do with practicing problems?

As a simple example take matrix multiplication, tests in linear algebra often asks you to multiply matrices. Now, do they do this to gauge how well you have trained your ability to multiply matrices together or is it to see if you have understood what matrix multiplication is? It is obviously the later since being good at multiplying matrices is a useless skill to have outside of that course. If you understand the process there is no need to do any exercises on this.

yes but to flip it over, would it be good if you knew what matrix multiplication is, but didn't have adequate practice into actually being able to calculate it? I feel this is a dumb argument lol, as we both know that understanding the concept is JUST AS important as being able to calculate it... I just feel that practicing calculations makes the calculations themselves second nature to the person, and that is the goal of learning anything.

I just realized after rereading the OP's post that he didn't mention anything specific at all..
what is your major anyways? I think all of us just kind of assumed physics. or do you have an unrelated major, and are just taking science classes for credits? It sounds a bit off, and I don't quite understand you regarding learning as simply "accumulating knowledge" because what good is accumulating said knowledge, if you don't know how to use it. I could memorize the periodic table, but what good is it if I don't know anything about the elements themselves? Maybe a nerdy party trick, but what else? and I'm not understanding your connection between rigorously redoing old test questions in preperation. I don't see how that is just studying to pass tests, as it is basically you going back and learning well how to do the calculations. Also, most people can't sit in on a lecture and understand everything fully. It's all about the outside work. I generally feel that the nature of physics and mathematics IS the work you put into it outside. This isn't high school where simply going to the classes is enough. College is about learning things vital to what YOU want to learn about. To put it simply, you are speaking in somewhat a twisted manner. I love going home and pondering the subject matter of my class. I actually enjoy doing the calculations over and over, because I know that that is the only way I can get used to using them. if all of that seems unnecessary, or that you feel you neeeeed to do that stuff, maybe rethink your topic of study? Believe it or not, this field is a bit more than just a "sit and absorb" in its education.

Edit: Btw, I am not the OP, but I am currently halfway through a double masters in theoretical physics and maths.

but again, we're going around the same thing... the two are both needed. a conceptual understanding however, is a luxury that is not always possible. most quantum theory can't be conceptualized well, but one can gain a great understanding of it mathematically. And understanding it mathematically, is nothing if you don't know how to use it mathematically, and this comes from practice.
