derivatives, imo. time series is easy once you have a good set of notes to work off.

I found the following difficult:
-Time series analysis in quant (only b/c I didn't feel it was worth memorizing the vast amount of info for at most 6 questions on the exam!)
-Exchange rate topics in economics (esp. triangular arbitrage)

Everything else wasn't that difficult after you put in enough time. The two topics I spent the most time on though were pensions and intercorp investments in FRA just b/c FRA was so heavily weighted in the exam and you were sure to see these topics on the exam.

Quant is rough, IMO. Aside from memorization of pension accting and intercorporate investmentments I didn't find any particular topic that difficult. Howeever, the challenge lies in the vastness of information and time it takes to get a firm grasp of all the concepts, in addition to questions posed in vignette format which adds another layer of difficulty. Given 5-6 months of consistent study you'll have reasonable shot at passing. I put in about three solid months and feel 50-50 on chances of passing, had I started earlier I'd feel quite confident. Put in the time, don't get bogged down, and do all CFAI EOC questions, several time for key areas.

I do not know as to which is the most difficult LOS in level 2 , but I can assure u it should be from Quants section.
