I really did not spend as much time studying for this section as I should have.. Mostly because I hate math. But bootcamp and math destroyer are all you need! I may have gotten lucky or maybe all the dat exams are like this but my exam was much simpler than anything I had used to study.. But destroyer and bootcamp helped a lot. Consistently ran out of time for destroyer exams and bootcamp and got 15-18 on QR practice exams. Real dat: plenty of time, got a 21. Good luck!
