I have taken several training coarse's from TecHelp. including update training for smog and the A6/A8/L1 training and a lab scope class. Doug and John do an excellent job in teaching anything from basic to very advanced information. They are brilliant instructors and provide a productive entertaining learning environment that is second to none. They provide hands on scope training that is very impressive and unique in that you the student are actually hooked up the car using your own Scope live. This is the best way to learn just what your snap-on, pico ats or other tool can do. I have gotten very high ase test scores after taking their training coarses. If you really want to learn something I highly recommend taking classes from TecHelp.
