About car transporter job

Andrejs:
After a long process I found a company that agree to take me for this job and teach.Will be 2-week training, wages averages.THe give me a trial. From 3rd atemp I reversing van to top decker, big pressure to the neck. But can you say what basically the biggest mistake for a new car transporter job after training? What must do more carefully than teach at training?

Just wondered what Grammarly.com would make of it - install it on your computer or phone and select options from highlighted errors (it couldn’t understand atemp).
