The DAT is very tricky, you might a few plant questions, a lot of plant questions or none at all. Unfortunately that is the nature of the DAT. There is no way to know prior to the test what you will encounter. It has been stated by some that the DAT Destroyer is overkill, I must disagree because it will prepare you for whatever comes you way. No one has a crystal ball to know before hand.
Hang in there, the DAT is very challenging but a very manageable test if you prepare for it. No shortcuts or easy way out to achieve a high score.
Just my 2 cents.
Wishing everyone the best.
