In general, one of the problems of trading is controlling your feelings, even using simulation models may lead to good results, but when you start trading real, feelings lead to many mistakes. So learning how to control your feelings is the most important step>.

I believe what you mean by feelings here has something to do with greed control. Greed is what kills most people in trade, so please urge him to learn to control that too by the time he graduated with your practice guide.
However, I would enroll myself too with your practice tools as I'm still a student.
Thanks in bunch
