I do think it's test taking anxiety, I did around average my first year, and then my grades started going down second year which is when I think the anxiety started, but I didn't realize it, I just kinda assumed I was dumb or wasn't studying hard enough, and it was frustrating because I wasn't doing well no matter how hard I studied.
It wasn't until my first COMLEX failure that I met with a school counselor who told me I might have test taking anxiety, so the second time around I tried to just keep it under control and consciously stay calm and I felt okay coming out of it, and then almost passed with a 393. Then this third time I thought that since I studied so much and my scores on the test banks were always well above average, I should be fine, but I basically had a meltdown in the testing room because this was my last chance and the anxiety really got the best of me, there are 2 incredibly easy questions in particular that I can remember I got wrong just because of my nerves and I'm beating myself up every day because of it. If I pass this test, the first thing I'm going to do is get some serious help for the anxiety.
MCAT wise I got a 506 (which averages to around a 29 I think using the old system)
All I can do now is just wait and see, it's pure torture, I'm going through FA to see if I can jog my memory and remember questions that I marked to see if I got them right, and surprisingly I'm getting more right than I thought, but also getting a few wrong as well, so its a mixed bag.
