Hi, I'd like to get opinions on getting a single subject credential in math from National University in Southern California. I was planning on applying to Cal State San Marcos or San Diego St and thought I'd have no problem, but San Diego St requires 30 hrs of observation time and San Marcos requires a recommendation from a public school teacher. This would be a career change for me. Right now I'm working full time and I graduated from college back in 1999 with a biology degree, but math was always my best subject. I'm nowhere near my high school and it's been 15 years since I was in high school so there's no way I could get a recommendation from one of my high school teachers. Working full time, it would be hard to get those observational hours. National University doesn't require those so that's why I'm looking at them. Right now I'm just studying for the CSET in math and plan on taking the CBSET after passing the subject test. Any info would be appreciated.
