I have been messing around with Qbank for about a month now. I have taken about 200 questions, mostly random and timed. I get anywhere between 40 -70%, but the vast majority are around 50. I decided to take a block of questions relating to my last test block in school, in this case, the endocrine system. So I did a 50 question set of all subjects in the endocrine system, and what do you know, 84%. Not great, but an improvement. So for everyone out there getting pissed off because you are getting 50% in qbank, study a certain area, then try taking questions over that area you just studied. You will see a difference. Bottom Line: We are going to need to study for this exam! So I am going to stop taking random question sets for now. It isn't worth wasting the questions before I have started to study.
