I'm talking about looking at the class average and grade distribution to assess how I do on a particular exam.
Just be careful with this. If your class is particularly studious/competitive (like mine is), then you may find yourself consistently at or even below the average for most tests. And that is okay. Really, truly, it is. As long as you pass. Don't get too caught up in comparing yourself to others or even the curve too much or you will start feeling miserable about yourself.
Let me put it this way. We had a path exam a couple of weeks ago that has historically had an average in the 70-85 range. I was absolutely stoked to see that I made a 90... until the professor said that our class average was---get this---a 97. Most of our tests have gone that way, and sometime I've been SIGNIFICANTLY below average. There was another test at the start of this semester where I made a 65 and the average was 91 (and I wasn't even the lowest score, either). It is upsetting and it makes me feel completely incompetent, but I'm trying to shift my attitude about tests to a more positive one of "Eh. I'll do what I can, but I'm not sacrificing my mental or even physical health to try to break into the upper part of that distribution." And, if anything, my grades have actually improved a lot since I just stopped worrying about it as much. Seriously, last semester I was an anxiety-ridden mess because I was so afraid of being below average that I did nothing but study. I wound up burning out and crashing halfway through and finished with a GPA just barely high enough to avoid probation. I wouldn't be surprised if I was bottom of the class right now.
Man, I really do love most people in my class but there is a small but vocal minority that really ruins it for everybody. There's been several occurances of cheating and yesterday, upon it being announced that class ranks are available, a lot of them started asking other what their current GPA and class rank are. That isn't okay. I have one friend who has been told that she can't study with a certain group of people because she wasn't in the top X% of the class... things like that. Heck, I won't even mention my specific grade to people when asked---I'll usually simply say something along the lines of "I feel that I did well/not well" and leave it at that, so the fact that people are discussing and comparing specific metrics like class rank and whatnot astounds me. I am just desperately, desperately hoping that they start chilling out a bit after this year. The c/o 2018 and 2019 seem more relaxed in comparison, so maybe there is a chance?
Anyway, sorry that I went on a bit of a tirade there. Haha. My main point is that while you certainly can look at your average scores and use it as a guide to figure out whether you should be working harder or maybe even a little bit less towards preparing for tests, you shouldn't look at them as metrics of self-worth or ability to be a good doctor. Don't define yourself by your grades... right now you will probably say that you won't but is scarily easy to fall into that trap in vet school and it will send you spiraling down into a unhealthy mindset very quickly.
