Dool, I posted some suggestiong on Predental forum regarding QR, you might find it helpful🙂
Dentaldreams, I think many of will agree that QR on the real test is both a little harder and easier. I think it is easier because it doensn't question you on many formulas you might know. I hardly had any questions requiring to find volumes of complecated objects. But I thought the QR on the real test was harder, because I was totally tired from the previous sections and you need all the concentration you can get. Many of the problems were straight forward but required much calculation, and that takes time. Top SCORE QR is pretty close to the real thing, but without the weird geometry and probablity problems (some of the prb problems on the topscore were very weird, requiring you to do like combinations and stuff) I have simple red ball and white ball problem.
Regarding the formulas, well you can spend like 20 min memorizing the volumes and stuff, i think you should be
ok.
Good luck,
Balki
