I'm in a international med school, end of my 2nd year and hopefully I don't fail out. I recently took an exam from my school. It wasn't my best but it wasn't my worst. 

The thing is the way that my school grades these exams they grade on a bell curve. So even if I do get the 65% I need, if rest of the class does a lot better I can be put lower down on that curve and even have my grade lowered cause of it.

Let's just say avg was like 85 and I score a 70, it will be curved to an 80 and then put on a bell curve. Well if I am in the lower bottom half, there's a risk I can have my grade lowered. Cause if the standard deviation is like a 10, if I'm in between -1 and -2 standard deviations from the mean my grade changes from that 70 to something lower between 60-70 or even lower depending on how I do compared to others. It's confusing but the previous class had people fail because of this. And that's what is driving me insane. I don't want to be that unlucky person who got f'd by a bell curve and ruin my entire career.

I failed one semester already a year ago, had to repeat that semester. This semester I'm still passing currently but because of previous experiences of having failed I just haven't been able to do anything. I haven't been able to study for another exam I have tomorrow. This one doesn't matter as much cause I can retake in February if I don't pass it. But if I fail the one I talked about or get below a 65 I'm screwed. I will most likely be dismissed from my school, I have close to 300k in debt, I'm just petrified. I don't know what to do if it that happens. I'm so nervous and I haven't been able to talk to anyone around me cause of this. The amount of anxiety I feel whenever I think about this test is driving me insane. I just can't function. I'm crying everyday because of it and I can barely sleep. 

I keep trying to justify the previous exams, where the class had an avg of 70 (some exams lower at 63 and some higher at 73) which is the scaled to 80. I  scored on avg around a 73 on the exams with the curve some better and worse. So I am below in the 0 to -1 range I think. I'm just NERVOUS AS FUDGE that this pass exam I fucked up even more which would push me into the lower -2 or even -3 standard deviation range. I'm just hoping everyone else was either burnt out or thought the exam was difficult too... I just don't want to fail... I'm scared.
