Does anyone know where my son can go to take a prep course before sitting for his License Exam?

Welcome to ECN first-off.
I see from your profile you are from North Jersey. A good thing, as I am also a Garden Stater.

I have a contact name for an instructor who does exam prep, and the CE courses. I don't want to post it here, as it may be again-the-rules" I will e-mail the info to you direct.
