Better than a classroom course...

Students who use my self-study course have a higher passing rate than students who attend a classroom. Plus, they save a lot of money
WHY?
Because, people who READ the material retain much more than people whom are TOLD the material, and the Guide is always next to them for reference or as a last minute refresher. In classroom courses, one of the most common statements made during breaks is “I think I’ll understand this stuff better once I get home and look over my notes” (Translated; “ I don’t have any idea what he’s talking about, and I’ve only got 1/2 page of notes.”).
If your looking for a source to help you learn the provisions of the International Plumbing and Gas codes, look no further. This course takes you through each chapter, step-by-step. It leaves no stone unturned. It explains water, drain and vent pipe sizing, how to calculate fixture requirements, occupancy loads, male/female ratios, gas pipe and vent sizing, and combustion air requirements.
