schweser are good, CFAI lets you get one mock exam. other exams are really not meant to be mock exams and do not give you as much of a feel for the real thing (CFAI mock is best for this).
someone mentioned the Boston Society had a good mock exam too (google it).
I have a question regarding Schwesser practice Exams. I have all of 2009 practice exams and Schwesser 2009 notes. I haven't seen much of a difference between last year's notes and this year's notes so I'm thinking that using last year's practice exams will still be pretty good preperation for this year. I just hate to buy new materials over again if what I have is pretty sufficient. I know that no one can really definatively answer this question but does anyone have an opinion?
I think the L1 exam is pretty generic -- it covers more academic basics, so I wouldn't expect much change from year to year. But then, do you really want to risk failure?
