I need some advice, so I'm getting it from everywhere I can. I'm a third-semester master's student in mechanical engineering. I've done well up to this point, but I took a fluids dynamics test yesterday that is sure to be a disaster when it comes to the grade. It was not hard, but I made mistakes that I normally wouldn't make (mainly solving some of the differential equations. They were easy DE's, too.). I haven't been able to sleep last night or this morning just thinking about the possible grade. It looks like a 60 or a 65 are most likely. Since the test wasn't hard, I'm pretty sure I'll be below average. What do I do? I don't want to make rash decisions without having the test back or before the semester ends to see where I am, but I feel sick just thinking about it. I've talked to family members and friends, and even though those talks helped, I still feel sick. In fact, I feel sick just thinking about the mistakes I made. After I submitted the test, I was able to work out the problems correctly on my own. It's frustrating to know that I can fail this test not because I don't understand the material, but because of foolish mistakes in easy mathematics. My thesis is done, and is being reviewed by my advisor. I have one class left next semester, and the other class I'm currently taking is good so far. It's just this one class. I can't make below a C, however, in any one class, and I can't have my GPA be below 3.0.
