Hi and welcome, Where are you from? Where are you at right now? Are you in a traditional college? Which one?

In short, the CLEP is a type of test you take to show knowledge of a subject. If you study adequately these tests tend to not be very hard. In my opinion CLEP sociology was the easiest CLEP.

If you are going to take psychology my advise is to buy an "idiots" guide to psychology. They can be found at almost any books store. The "idiots" guides are written for a bunch of different subjects. Read that book first and it will give you the basics. You can also use instantcert to help with your studies OR buy a used psych book that is (slightly) outdated. This will save you money. You don't need to go overboard on your studies, but you do need to know the basics. On average you will need to get about half (or slightly more) correct to pass. Good luck.
