South Florida Technical Training (SFTEC) Has been successfully training technicians to pass ASE certifications for over 12 years. We have trained hundreds of students to pass their ASE certification test. We are currently putting together our online version of our training program. We are looking for a new location to offer our hands on classes.
For the last 12 years we have been teaching the classes using hand outs and power points. There are about 60 slides per class day. I have been recording the classes and making videos for years and am putting that together with our videos and questions to make the online program. This video is just 10 slides of the 60 slides for engine performance day 1 Fuel system. The engine performance fuel class has over 720 Slides and 100’s of videos. Everything is done in short format and changes on average every 60 seconds.
The questions below are examples of the questions we ask on these 10 slides.
