I took the CSET Single-Subject Math Subtest #1 for the first time this past Saturday. It was a difficult test, but I did a bit better than I thought I would. I don't think I passed it, but who knows. <EDITED> The multiple-choice ones weren't too bad, but there were some I had no clue on and some I had to make an educated guess with. I think I definitely got 20 out of 30 right, while I had to either make an educated guess on, or had to just make a random guess on the rest. Study up on rings and fields...that's all I'll say on that end. Know vectors, matrices, complex numbers (in the form of a + bi), etc. I hit my dead end at 4 hours into the test. I spent the last half hour memorizing the problems I had trouble with. After the test I went outside and wrote down all I could remember. Also, all the math I have ever had outside high school (graduated in 1987) was 1 semester of Trig and two semesters of calculus...the last algebra class I had was in 1986 during my junior year in HS. This test was hard for me, but not out of reach. Keep your heads up if you have failed, and try again. Also, I took a prep class at National University...it was well worth it...and I get to take it again for free if I failed the test.
