Whatever you do, do not take schweser's 3-day seminar. I used a strict self-study program and by late March I thought I needed to supplement my own work with some live instruction so I signed up for the 3-day seminar. It was a waste of time and money. The instructor was very intelligent but to cover all the material in the limited time (~20 hours of instruction) we were on a powerpoint death march, which could have been easily replicated by going through the study notes on your own. If you are considering using some sort of instruction, the weekly classes or the lecture cds might be worth it since you have more time to cover topics in detail (and not just skim everything). Keep in mind, I did not use the cds or live classes for L1 so I can't say if they are helpful or not, but if you have problems staying on track the weekly classes may provide some structure for you (which you need).
I just sat for L1 in June and if I pass (knocking on wood), I might buy the lecture video cds for L2 since I travel for work. Does anyone have any feedback on the lecture video cds?
