Hey skybluemaniac,
Personally, I found the A+ notes to be fairly average when it comes to study guide value. The questions were alright but sometimes too simplistic and too few- despite its claim that it provides exam style questions. The notes were very basic as well - mostly just summaries of stuff you already know.
I never actually bought the book as my school library had a couple of them in stock. So before every SAC I would borrow it and do all the relevant questions and glance through the notes etc... Not. A. Single. Question came up on ANY of my SACs.
On the other hand, Neap, Lisachem and Checkpoints were fantastic in terms of question quality (probably the best out there). Having said that, I still own Neap and Checkpoints 2013 (pristine clean because I did the questions in a notebook) if you are interested.
Regards,
PB
