When I was working on my certification for HVAC repair, I had a lot of trouble with the classes. A few of my classes were held online, and I didn’t study very hard. I was hanging out with my friends until all hours of the night. We studied infrequently and drank beers all the time. I didn’t pass the first time, and I was forced to take the class over. The second time, I had to pay out of state tuition prices for the HVAC prep class. I really wanted to pass, so I looked for some practice tests online. My Dad wasn’t going to pay for the class a third time. He was already mad about the tuition price, and I needed to pass the class. I knew my Dad was serious, because he threatened to take my car. Luckily, I found some great online resources to help me study for each HVAC test. The online quizzes are broken up into different sections. There is a practice test on furnace repair and another test for air conditioner repair. There is another test that deals with indoor air quality problems and ventilation systems. I missed a few questions on the last exam, so I have been practicing the online tests each night. As soon as dinner is over, I am sitting at the computer with a study guide. I’m going to retake the certification test in a few months, and I really want to be well prepared. I only failed by ten points last time, and that could be one or two questions.
