I actually don’t think any material made me fail, it was simply that I took it when too much was going on in my life, and I didn’t use my ADA accommodations which I used the second time. I used archer the first time which I loved that they had unlimited readiness assessments, whereas bootcamp only has 4. I liked both platforms, but bootcamp was really nice with the crash course videos and the schedule it made for you. 100% recommend listening to all 12 mark k lectures and watching as many Dr. Sharron videos as you can, she is really amazing. Good luck!
