first ochem exam

I feel so stupid. I just took my first ochem exam and it was miserable. the first two pages were great, and I was like wow, maybe my studying paid off! and then i genuinely just stared at the next pages with no clue what to do. the thing is ive literally taken ochem before in highschool 3 years ago so i should have done better. idk. my prof is rated highly on ratemyprof but it's because he's genuinely a great person, but his tests are impossible. i feel like im not cut out for medicine bc i have never felt that horrible about a test. i studied, but i don't think i studied as thoroughly as i should have. the sucky part is that i have no one to blame but myself. my professor has a policy that if you get an A on the final you get at least an A- in the course, but if the final is anything like this exam, there's no way I can do that. ugh. does anyone else feel really fucking stupid ?
