Me [M19] Her [F19] in a LDR because of college. Dating over four months.

We have a great relationship and we love one another very much. There are a few issues that come up from time to time, but we always talk about them and always do what we need to do to right the wrongs.

She is very dedicated to her school work. She is driven to get a 4.0GPA in university and I am very proud of her.(I tell her that too!) She keeps falling short by just a bit. Right now she has above a 3.8 which is fucking hard if you're an engineering major. EVERY TIME she doesn't get a 100 on a test, it ruins her day. It doesn't just ruin her day, it makes her **fucking depressed as hell**. I would be upset if I didn't do so well on a test as well, but she becomes *extremely* angry and irritable and annoyed. Sometimes it really takes a toll on me. 

I want to bring it up but don't know how. Of course, I can't do it while she is upset(like today). I supposed I should wait until I am with her next in a week and a half.
<bot>: Girlfriend becomes extremely angry after a test if she didn't get a 100%. She is dying for a 4.0GPA and really puts in the effort. How angry she gets seems unhealthy. What insight does reddit have?
