yeah i am the AJ that worked there, ASE isn't open book test, the last 4 i took wern't anyways, the only reason i take them is the area service manager for GM gets on my case about them, that and GM traning. i have been a tech for 4 or 5 years at GM dealerships so i do have alot of skills behind me and i'm not taking anything seriously, i mean this is the internet. but out of the 4 test i have taken i did pass all 4 witch are electrical, engine performance, steering and suspension, heating and a/c. they may just be a piece of paper but i have a better chance of getting a job at a shop than someone with out them or less of them than i do.
