I recently took the CBEST, which is a test that you need in order to become a substitute teacher in California. I do have a four year degree. I think I did fairly well on the test since I took 3 practice tests and I read a prep book front to back. Now, if and when I do pass and I finally get credentialed to substitute, I think I'm going to have a mental breakdown. I have worked with kids before ( tutoring) but I haven't managed a classroom full of kids. This scares me. Anyone have experience substitute teaching and advice for me that I can use when I actually do start? TIA.
