Schweser 3-day Review

My boss said that I could take a review course and that it really helped her years ago in passing the exams. Is the Schweser 3-day review the best one to take, regardless of the cost? I am mid-way through book 5 of the CFAI materials and should be finished by mid-October with Book 6. I wished I had gone with Schweser, but I didn’t find this forum until midway through my studies. I am not too confident with what I have learned, though I see that is a common emotion, and that a lot of learning comes with the Q-bank. I haven’t gotten that yet, but I will be using it a lot with my review. Thanks, and any more guidance is appreciated.
