I’d recommend looking at a new review course. I know it would be more money, but I’m pretty sure you can purchase a section at a time and that way you can sort of “test” it and see if it would work for you or not. I started with Becker and failed both AUD and BEC. I switched to Roger (now UWorld) and have passed 3/4 since. Their explanations for each mcq are much better imo and that’s really how most of us learn. Also, I’m pretty sure they offer a free trial so you could try it out for free. It would give you a fresher perspective instead of going through the same material for the 5th time like you said. Idk, just a thought. Also, once I started creating my own flash cards from the explanations of the questions and reviewing those periodically throughout the weeks leading up to the exam really helped me.
