I am planning on taking the sociology CLEP test shortly and after reading the reviews have just signed up for instacert. I am now a little concered, its just fill in the blank flash cards?? Maybe I jumped into buying it too quickly. How is it supposed to prepare you quickly for a CLEP with flash cards only. There is no other types of study material right, am i missing something. I dont know much about Sociology, how am I supposed to do the flashcards at the beginning?? stressed!Any previous experiences or advice would be very appreciated.
