Last year's level 2 exam was almost worthless. They don't word the questions as well as the CFAI, they had multiple errors, and the whole day probably would have been better spent studying than sitting there doing that.
I think the Schweser mocks are better than that exam.
1 - They horribly screwed up a currency exchange vingnette. They mixed up USD:EUR, literally wrote it backwards.
2 - Then they left off a correct answer to a calculation question...
3 - Then they actually got a numerical calculation WRONG in another question...
Not impressed with BSAS - looks like they didn't even have anyone TAKE the test before they sold it to people. Would not do it again and recommend others stay away.
Also thought it was much easier than the test will be.
