Today's Technician: Medium/Heavy Duty Truck Diesel Engines Classroom Manual & Shop Manual 1st Edition

Purchased for my on personal knowledge not a required buy for me. Found to be an easy read that was also easy to follow.

I am very satisfied with the service, shipment, and price of the books! I'll definitely buy from again! Thanks again!!

I'm going to write the same review for all three of the ASE Test Prep guides I purchased.To be honest, I'm not very impressed. I'm used to the study guides for the FAA flight tests which are generally excellent from everyone. These had typos in the questions. One question even said to refer to a diagram which they forgot to print! I also found several mistakes in their subject matter in the study section.I think they are an aid and do help with the preparation but they publisher could have done a much better job especially for the price.
