hi guys. i was wondering which of the examkracker books to buy. . .there's a 5-volume set: the "complete examkrackers guide". . .does that include everything (ie: the 1001 study questions). . .they didn't give a description of which books were provided. . so, does anybody out there know what that set includes?. . .or what, i should buy so that i can get the complete set (how many books are there total?) also, is it true that examkrackers does not provide answers and explanations to their questions? thanks for you help guys.
