What percent should I get before taking

Hi,
I would say that one should be getting high 70's and low 80's should do it for Q bank and Q book. If one is not getting at that level, I would suggest that you need to read more and then redo the questions. Scoring high first time around is not as important as understanding it. Once you repeat the questions you will find that it will make sense the second time around. Most people (FMGs) will initially get around 50s and 60s. But once they get the hang of it, the scores will rise. Hope that helps
