Ringing Ceders

I would really like to get into a good university, but in order to do this I need to get a good score on the TEFL. I want to find a good tefl course, can anyone tell me how to go about doing this? I want one that will do a really good job helping me to prepare for the exam. My English is really pretty good now, but I am required to take this test, and I am worried that I might mess up on something silly. I don’t want to not get in because I can’t pass this exam.
