Hiya Stokey,
I am in the same boat as you when it comes to Contracts / Sales
My plan was so use my CPA reivewers material and re-write my own notes on those topics. Do batches of 20 question and see I am doing well. If not, I would re-listen to Jeff's REG Audio for those chapters as sometimes just listening to someone talk on a topic helps.
I am not sure if BLaw is never tested as a SIM in the actual exam. I read it somewhere.What I would do is SIM's on Contract/Sales in your test bank. I some times find by doing the SIM question it really helps to you understood the subject material or not. Sort of helps give you a bigger picture.
Lastly but not least – I would reach out to the folks here and show them the question, ask for help understanding why its Ans A and not B etc. I am sure someone out here would have a better foundation on it and is willing to help you understand it.
FAR 05/27/14; 786/110 - Done !
