While running a contractor license school, I learned that the biggest difficulty guys faced was that most of them had not taken an exam in years.

  • Some of my students did not finish high school or had immigrated to the United States recently, and were still learning English. 
  • One of the best study tools for them was to use Online Practice Tests. Simulated online tests are based on the state exam.
