I read Economics as an undergraduate. Naturally, most of my decision making rely on optimisation considerations. When I took December Level I, there were a lot of "heck, just-do-it" experiments to find out what worked and what didn't, in order to make the most impact with the least amount of time I had for my CFA studies then.
The good news? You don't need to repeat that discovery process, as I've summarised the best practices you need to pass Level I, Level II and Level III (in one-go, preferably). All you need to do is apply these techniques consistently, track your progress and see the difference for yourself!
So what do highly effective CFA candidates do?
