By now, many of you should have already completed at least one midterm and gotten back the results as well. Hopefully, you're happy with your scores, but if not, don't worry! It's not the end of the world. We all know what it feels like to get back a midterm that we didn't do so well on. And if you're feeling discouraged, there are a few things you can do to better prepare for future exams.

First of all, look over your test and see what you did wrong. I know it seems very basic, but sometimes we can neglect to do this out of our repulsion of the exam and the grade we received for it ( I know I tend to have an "out of sight out of mind" view of midterms..). Knowing the kind of mistakes you made can help you understand what you need to study as well as the type of questions that stump you. Then you can focus on how you can better prepare for the next exam and work on your test-taking skills.
Also, it doesn't hurt to go to office hours and talk to your GSI and professor. They can show you what you did wrong as well as give you a better idea of what their expectations are. They'll most likely also tell you what you should study more for.
And most importantly, don't be too discouraged! There are always more chances to improve your grade and to do better on upcoming midterms. Many classes are curved, and for the most part, you end up doing better than you would expect. Things always even out in the end!
