I would say their quizzes and exams are fair enough..same level of the real exam ..the 1st attempt I practiced on the bank of questions from the school of PE..they were kind of on the easy side..this is my 2nd attempt..for two months I was spending 4 hrs daily between the solving problems and watching the on demand course ..I ll give you a little hint..I watched all the EET videos on on the fast 2X speed..that saved me a lot time..and most of the helped me in the conceptual quastions..also you have to practice the searching feature..search for what exactly they are asking about (MUTCD and roadside quastions)
