Experience using ExamSuccess?

I’m temped to use materials form this prep provider, I liked the youtube stuff I see and I do see them listed on CFA institute’s website.

I’d be interested, can anyone comment on theirs.

I also go this coupon, SAVE50, in an email, passing it along for anyone who wants it. Its for 50% off their stuff https://courses.examsuccess.ca

Thank you in advance.
