OP, please take the comments and advice you have been given here seriously. The posters are giving you real life advice, whether from themselves or others of us who have kids th a t have gone through the process.
The biggest red flag to me is your rationalizing standardized test scores. Med schools won’t care that you do well on practice MCATs, residency programs won’t care that you couldn’t think straight the morning of your Step 1. The simple truth is that scores DO matter, and those tests are never ending. My kid is a PGY2 and is on her second day of her Step 3 test which is 16 hours over 2 days.
Seems like you have turned your HS GPA around, congratulations. I don’t have any advice for your test anxiety, maybe others have some advice to overcome that. Good luck.
