Agree with everyone else. Fix the mcat.
Definitely use Anki. If it feels uncomfortable to use anki, keep practicing and get used to it.
Anki took me from getting 4's -7's on the old mcat scale (baaaad percentile) to 508 on the new mcat in 1 month (cus I was tired of my job).
But you NEED to do well this second time around. if you feel unconfident by the end of the exam, VOID IT! DON'T SCORE! And then study and retake it.
I voided my MCAT 2 times before scoring the 3rd time, so I ended up with one score of 508 instead of what would have been, scores something like 47X, 47X, 508. That would have been a game ender.
