Anyone take the College Algebra CLEP?

I’m preparing for the College Algebra CLEP and wondered if anyone who has taken it can give me insight into its difficulty. Math has never been my strongest or favorite subject-- I understand the concepts, but I lack confidence in this subject and often get nervous when solving problems. I’m preparing for the test with the REA study guide and Khan Academy videos.
For reference, I scored a 590 on the (old) SAT math section. For anyone who has taken the test: How difficult is it? What were your favorite resources? Do you think this test is doable for me with my history in math?
