T-Ten requirement for passing T-Ten certification was passing 2 ASE exams. I think it's a good program because it's an introduction into working on all kinds of vehicles. The Toyota brand has a reliable hybrid synergy drive, which is important to understand.
I have passed quite a few ASE exams, if you aren't aware of ASE exams what they mean let me explain for you.
A lot of this stuff about hydraulics, fluid motion, and other mechanical concepts is very useful.
