So just finished DAT today.
PAT 21
QR 25
RC 24
GC 21
OC 22
BIO 21
Total Science 21
AA 23
I studied 3 weeks in total. Quickly reviewed Sciences in 1.5 weeks and strictly did Bootcamp for last 1.5 weeks. Bootcamp is the closest you will get to the real exam. RC, Bio easier on real exam. Similar in terms of OC QR PAT, but GC was slightly harder. Cheers
