FM Book

Just want to know if anyone bought this book for Exam FM? Is it really helpful or am I better off just studying the free ones online? The author classifies each SOA sample question. They also have this stuff for Exam P.

P: https://play.google.com/store/books/details?id=fEIQEAAAQBAJ

I think it depends on how familiar you are with math regarding these two books.
I checked out the sample and found the books are very math notational heavy which might confused those who are career changing or coming from a non-traditional background.
