Yeah you're probably good on Qbanks. You're in a nice position and would probably already pass. What I did was keep a running list of the stuff I was bad at (vaporizers and other anesthesia machine questions, stress dose steroids, those invasive pressure waveforms overlapping with ECGs, etc) and reread those explanations. I had a notebook where I would force myself to re-summarize that stuff from memory. I had ambitions to go through the BASIC content outline as well but I honestly can't remember if I actually did that.
After that I had some time to go through (rapidly since at this point I was recognizing the questions) TrueLearn and spot re-reviewed M5.
I don't mean to stress out any time-poor CA1 reading the above. This is what I did with the intent of snagging top 10%tile. That's not where I normally live with these standardized exams so I put the time and effort in.
