I was skeptical at first having to pay for a PERT study course but I am so glad I did. I hadn't done any math since high school which was 7 years ago for me and I didn't remember anything at all. But I followed this course for 2 weeks and in that time I learned more than I had at years of school. I scored a perfect 150 on my PERT and because of it I got to take the Accuplacer and scored well on that too which placed me in Pre Calc and Trig! It saved me from taking over a year worth of lower level maths and thousands of dollars. The structure of this course was by far the most efficient way I have ever been taught math. The clear explanations in the short videos and practice questions afterwards makes learning the material so easy!
