hi
Each of those simulated practice tests has its own strengths and weaknesses. for one, questions in toppro especially the science part were harder than the ones in a real DAT, and this is also true with kaplan CD. as for the QR and Reading, i think toppro was very similar to the real test in terms of level of difficulty, the format of Reading.
As for Kaplan, i think it does a very good job preparing you for PAT since it provides 3d constructed answers for the first two sections. however, i find RC to be quite different from the real test, again in terms of format and to some extent level of difficulty.
if u really want to do well and increase ur chance to get into dental school, i advise you to take kaplan. i am not in fond of the lectures although it's a good review, but the practice exams/review questions were worth the money. and also do diagnostic, midterm, and final..
what helped me the most is their explanations to wrong answers choices and indepth explanation of an answer choice.
and one more thing, be careful on angle ranking section. lines were longer and bigger, and they screwed me up. maybe because i was taking all of my practice test on 15 monitor, or maybe the lines are really longer.
anyways, i hope this helped.
