Scored a 98. I looked at all the past CBSE threads for tips during my preparation so I feel obligated to contribute some thoughts.
Background: currently a D2 with a pass/fail dental curriculum so I essentially focused on studying for this exam for 5 months straight while my dental classes were secondary. I was fortunate that my first year medical curriculum helped with the more challenging concepts (especially in neurology, renal, respiratory, and cardiovascular) so I was not learning too many things from scratch.
I used First Aid (2x), Pathoma (1x videos, 2x text), SketchyMicro/Pharm (2x), UWorld (1x), and NBMEs (13, 15, 16, 17, 18, 19). I started by going through Behavioral Science, Biochemistry, and Microbiology in First Aid. I watched all of SketchyMicro alongside FA Microbiology. Then I started the first 3 chapters of Pathoma alongside FA Immunology and Pathology. For the rest of Pathoma, for each organ system, I would read the corresponding First Aid chapters and watch the relevant SketchyPharm videos. Finally, I finished off FA and SketchyPharm psychiatry.
With my foundation set, I started doing UWorld on random, untimed, tutor. I actually answered all the questions open-book and aimed for the highest percentage correct as if it were a game (ended with a 95.9%). This forced me to really research each question and the answer choices in First Aid, Pathoma, and Sketchy to reach a decisive conclusion. I think this process made me remember correct answers well, and by the end of nearly 2500 questions, I had most of First Aid memorized. However, this is an unorthodox and time-consuming approach so it’s probably not for everyone.
At this point, I had about a month left. I re-watched SketchyMicro and SketchyPharm at 2x speed (a lot easier the second time after UWorld). I re-read Pathoma and First Aid (which was also easier since I referenced them constantly during UWorld). I reviewed my UWorld notes on mostly low-yield trivia to cover my bases. Two weeks prior, I started doing NBME’s. The NBME interface is identical to that of the CBSE, so definitely do at least one to become familiar. 13, 15, and 16 were done casually for additional practice questions. 17, 18, and 19 were done timed on weekend mornings to simulate the actual exam.
I thought the actual CBSE exam was objectively harder than all the NBME’s. Comparatively, there were more questions not covered in the resources I studied. There were more times where I thought two answer choices were “correct” and had to pick and pray. I know for a fact that I got 8 wrong, and there’s certainly more that I’m unaware of. I thought I was going to underperform because I was getting fewer wrong on my practice NBME’s. However, the real exam had a more generous curve (perhaps to account for its greater difficulty) so trust your NBME scores.
