CFA cirriculum vs. Supplemental Material includes, opinion, current, decided, finance

towardsutopia21

Just curious if anyone could give me their opinion of solely using the CFA issued cirriculum versus using the Stalla or Schweser material.
Is anyone using just the CFA issued cirriculum or is that a bad idea?
Also, I’ve been out of school for 10yrs but i’m unhappy with my current career in Supply Chain Management and have decided to move to finance. I was checking the Stalla website out and one of the packages includes 18  inclass sessions but the cost is roughly $1300 (includes all Stalla material as well) Could someone give me their opinion on the inclass experience and how beneficial would you consider it and the supplemental material that comes with it given my 10yrs of being out of the classroom.
Thanks,
