I'm not going to lie, I didn't perform very well this first semester. Used to being the cocky, "smartest kid in his physics class" in high school, I made a few mistakes that I regret pretty badly. Mistake #1: I insisted that I could handle the workload and I jumped straight from Algebra 2 into Calculus 1. I had virtually zero knowledge of trigonometry, limits, and anything else you might find in a pre-calculus course. Mistake #2: I underestimated the demanding workload of a college education altogether. I spent a lot more time partying and wasting time than I should have. What really didn't help is that it was really easy to go through half of a semester without knowing exactly how bad I was doing until mid-term grades came in, and by then, I had no idea how I would catch up. (Of course, I spent a week or so pulling all-nighters and pulled through just well enough on finals to have low Bs and Cs in most of my classes.) Mistake #3: This is an extension of mistake #2 - I didn't take advantage of the resources I should have. The other freshmen were taking advantage of office hours, tutoring, and doing homework days before they were due, to name a few things. Naturally, I only started doing these things during the last few weeks. Is there anything that you think I should be doing as I go into my second semester? **Also, as a sort of post-script, I'd like to ask: have I just killed my chances at going to a good graduate school? I know that graduate schools look at both GPA and undergraduate research experience, and while the dent in my GPA might not be super critical right now, I worry that this first semester might prevent me from starting an REU in the near future, which, in turn, might make me less competitive for a good graduate school / job application in the more distant future.
