CFA candidates have forever been asking this question: What CFA study provider should I choose? Aside from the books provided by the CFA Institute, there are quite a few third-party offerings that can help you prepare for the exam. But, choosing among the many options can be overwhelming. Never mind that these programs are expensive. You want to pass, and you want to pass without wasting money. Basically, you want to pick the best one.
Unfortunately, there is no “best” exam prep provider. Really. However, I believe that you can create a “best” study program by using two providers instead of one. And, it costs roughly the same if you choose wisely.
