I just took the DAT on Sunday and to be honest I felt like it was a mix of easy questions with a few hard ones.
The hard questions were miniscule details that you may or may not have gone over, but its going to happen no matter what.
You're doing a little bit better on the practice tests than I was doing so it looks like G. Chem maybe one of your weaker topics. Aside from QR, G. Chem was my worst subject.
My best advice for G. Chem is go over the equations and how to solve certain calculation problems. I didnt go over any G. Chem the day before and once I got to the section my anxiety took over and I blanked out on like 4 calculations. Also go over the roadmaps for O-Chem before the test.
Just keep in mind that these practice tests are typically harder than the real thing. Once you get in there and sit down and start looking at the problems, you will start to realize that the actual test really isnt that bad.
Except for QR, screw QR.
