I didn't have to look them up. Its just that some of the questions are tricky, multiple choice, and I didn't want to fail the test. I still missed a couple. There is alot of info to learn and it is pretty interesting. I am not going to go into the a/c business but I needed to purchase 1 more pound of R-12 to finish my compressor/drier replacement. If you read the online material and can retain info, you should be able to finish the 25 questions fairly quickly. Good luck.
