After being unsuccessful on my Glass & Glazing exam twice, I decided to give BTES a shot. I took my class with Stuart and the Glass & Glazing test 1 week after – I passed with a 92.5%! The tools I learned in this class allowed me to finish the exam in 2 hours …that is half the allotted time of the test. I then took the Business & Finance exam 3 days later and passed with an 87%! I wish I would have known about BTES before I started trying to navigate these exams on my own. Thanks, BTES!
