Been there done that, HMEL #688. I will tell you that it is not easy. The test is 7 hours long, you will be in physical pain by the time you leave. The last time I checked part one was 125 questions closed book (2 hours). Part two is 5 hours with 10 multiple part questions. You should be prepared for Single family and multifamily dwellings standard and optional, schools, hospitals, offices (multistory), stores, machine shops, welders, elevators, 3 phase delta (high leg) problems that require balancing, an open delta was on the test that I took. Motor feeder problems, etc, etc, etc. You need to call San Jacinto South Campus, and get in touch with the instructor for Master's I & II. If you are in the Houston area, I would highly recommend that you go to the above classes. If you would like to discuss this further, e-mail me, and we can talk. Good Luck and God Bless.
