Definitely normal. Destroyer is obviously tougher than the real thing, but keep using it to study. It helps tremendously, and really makes the real thing seem easier. I took my DAT yesterday, and gen chem was tough. Bio and OChem were pretty straightforward (which for me was due to using Destroyer). Use Chad's and Bootcamp also if you can. Just practice as much as you can. That's the key. You'll do fine
