I would appreciate any comments or advice - I will begin substituting this fall. I am also considering going to school to get my credential. My initial interest was single subject - math. I enjoy it, would love to teach it, and thought it would be more marketable. I got my degree in Psych 27 years ago. I was 1 hour short of a math minor. As I look at the exam, I recognize the material, but I need lots of work to get back to solving the problems. My thought then switched to pursuing multiple subject, but I am wondering if this is as marketable. After reading some of the postings, it may take a while to get thru the CSETand only then can I start a credential program. By the time I finish, I will be in my early 50's. Is age a drawback in trying to get a first job? What are my chances of finding an K-5 position with younger competition? Would I be better off sticking with single subject? Has anyone gone from really rusty to mastering the CSET? If so, any special study guides, etc? Any advice or experiences would be appreciated.
