Hello everyone, I've been in the trade for about 7-8 years now. I'm getting around to taking my Qualifier exam and and looking for some help and pointer. I bought all the books and have been studying. I'm wondering what is the best areas to study and lock in on. Also wondering if any of the prep courses and exams help at all, I don't really want to spend another $250 on the prep but if it helps and I can pass my first time then I will. I'm based out of Wisconsin if that helps. Thank you!
