I have study manual for exam 1 and 2, study manual copy for exam 3 from a friend. Wondering anyone need it. I can sell for a cheaper price. I am actuarial science major before, however, I changed my major to statistics. So  I do not need it any more, the manual is pretty new. By the way, I have the exam 2 study book from my university (writen by a prof. in my previous university), very good one. I can sell for a very cheap price. Let me know if you need it.
