I passed all 3 levels first time using Schweser. I made my own outlines of the Schweser material as I went – like someone else who posted here, my outlines were sometimes 20 pages per study session – and occasionally consulted the CFA books if Schweser was confusing or sparse or I was just interested in the topic. Seeing words on a page is one thing; writing them down in my own words means I know what they mean, and when I re-review it later, it will speak to me because I chose the words. I can also make little handwritten annotations to my outline as I do quizzes/exams and get things wrong. I made flashcards as I went of key formulas/points and quizzed myself on the way to work. Although I had heard that Schweser was “weakest” for Level III, I did not personally find that to be the case. I used QBank a bit, but QBank in my opinion is less relevant for Level III, and I did two Schweser practice exams. Everyone else seems to recommend the CFA book examples, etc., but I did not review those myself. What I did do is spent a LOT of hours on the material, over a long period of time, and I made sure I understood it. I started studying in January and made a schedule, leaving 3 weeks as no-study weeks or catch-up weeks. I keep the CFA books as valuable reference material in my work, but in terms of cramming material in one’s head in a short time for purposes of the exam, I prefer the Schweser summaries. I believe one can pass with CFA books only, or with Schweser books only, but I think it really comes down to discipline, hours, and hard work.
