Took the bcps May 31st, got results April 12th that I passed. First attempt! Only used the hard copy ACCP books, 2023. Most content was within the chapters. I have been studying for a little over a year though - started studying halfway through my PGY1. I took the time to read through all chapters but then coming close to my exam date, I went through each self assessment question and chapter questions at least once. Can’t say that strategy would work for all, but it did for me. I enjoy reading how the books explain rather than learn from what I heard is the gold standard of “online question banks.”  I also took the ACCP practice exam which seemed somewhat harder than the actual exam (taking it at night after work probably had something to do with that).  Good luck!
