In my opinion, topscore was the best at reproducing the same level expected from the DAT. Achiever was waaaay to specific and had too many how many ofthe above are true I, II, iII, IV questions. And Kaplan was too easy. They often repeat questions time and time again, so if you get it the second time around on another practice test, that doens't mean you learned something, it means the Kaplan test writers were too lazy to write another question and you illegitamately got a question correct. this is not good if you want to get the best experience to actual DAT experience. . . Topscore again, was the best for this experience. . . .😱
GOOD LUCK!!! -- hope this helps
