I took the HVAC & Refrigeration exam and I PASSED!!!! Your step-by-step course really did make all the difference! This was my third attempt at taking this thing. The first time I took an in-person study course, a lot of theory, not great with the problem practice. The second time I tried to study on my own…not good. And my third time I found you and your course!

Your class was really great because I felt like in every video, you genuinely and sincerely wanted to help us pass this test. You are an excellent teacher, and the course is one of the most reasonably priced courses I could find and discovering that it was also so amazing was really a pleasant surprise.

Thank you so much for everything! Honestly, your course and teaching method really made the difference for me! I will definitely recommend your course to others I know who are considering taking the test!”
