Easy to understand the OP’s frustration here, but I’ll chime in from my experience.
I used Schweser for Level I and bought their stuff for Level II. I had found QM pretty hard, but when I reached Econ and FRA it was just mind-bogglong for me. The CFAI was NO help. Try studying growth theories in econ and pensions in accounting if you dont know what im talking about.
I was advised to buy the Elan video on pensions and it was explained so well (four hours long by the way). I switched over to their stuff pretty late in the day, and I owe them a lot for my eventual pass. Plus the guys there obviously are Arsenal fans too!! so they get my vote.
Don’t recall any issues with customer service (I probably just emailed one or two times) but if most of the material is available online already, then just go with the online package?
