Hello, I just got my CSET Math results and I failed both tests. As per my score report, I need help with the Geometry. I have to retake both the test and it is 3 weeks from now. I didn't use much resources: Prepping from Khan Academy, Pauls's Notes. Please Please share any study material. What you guys think about online test prep courses? What books I should purchase?? I have very less time to study. Any help is appreciated.
