Are those science courses? If you are still taking 100 level basic science courses (the ones required for admission, e.g. Chem 101) then it seems like you're applying to early.
i took a freshman level course my senior year and my pre-health advisor gave me a really weird look. she asked me why i was taking the course. i told her it was so i could review for my DAT. THEN... she she asked me if i was taking it to get an easy A 😛
