I took the level 2 test last Friday and can assure you it is way different then three years ago when I passed without studying. The math questions on here will help. But that's it, you will not see one question on here that is on the test. There are questions with more than one right answer and you must choose the best. I would say 50 questions I had were general knowledge that I had never seen before and took and "educated guess". Know your fuses, know grounding principles, the uses of meters and the leads associated . Know contact resistance and how it works, know one lines and symbols, know relays and symbols associated, good luck
