EPA Certification Test

roullette

Have a couple of questions on anyone whos taken the EPA Certification test.
Im taking the test tommorow and was wondering how tough this test is?

Im taking the Qwik608 exam from johnstone supply which i believe its a test from Mainstream Engineering.

the book i got is pretty good and im passing the 100 question exams in the back of the study guide. which i think that means im passing and could get my universal certificate if im not mistaking. my questions are

How tough is the test really?
what should i really memorize besides the Clean Air act dates and EPA dates?

Yeah, a lot of dates to remember. Get those dates down pat. Also, study the vacuum systems a bit too, to assure you pass. I took my test about 10 years ago, but I took a class for it and had no problems. The instructor said that historically 70% of those who take the test pass.

Check the pressure temperature chart for R-11. It's been years since I've delt with R-11, so I can't really say off the top of my head. I don't have a chart handy here at home. Realistically, you're likely to never run into R-11 in the field unless you start to service really old chillers, but these are the sorts of things test makers like to ask about.
