I'm a wimp or at least I'm very rusty. I want to become certified in HS math but I'm afraid of the Praxis. I was just about to sign-up for the exam when I noticed that graphing calculators were allowed! What's up with that?!? How often will I need to pull out that bad boy during the exam? I mean $80 for the test and another for the Texas Instrument to make sure I don't embarrass myself? I don't even have a job yet! How much have you put down to become a teacher? I'm confident it is worth it, but I'm just curious.
