I'm studying for the CBEST, and I'm wondering whether I should take the paper or computer test. With the computer test, do you write your essays on the computer? Is it possible to switch the keyboard mode to Dvorak instead of Qwerty? And is it worth the extra money to go for CAT instead of the more traditional paper? Also, assuming I pass the CBEST, what is the job market like in Southern California re: substitute teachers? I have a B.A. from Northwestern. Thank you!
