I've got my 7,6,and 63....Are you taking a class that your work is providing or studying on your own? I had a hard time with it at first but just keep on taking the practice questions- GL-
I passed it but had the company that I was going to work for provide a 2 month study course with check tests and online tests to take. I failed the 63 since I took it 2 days after the 7 and didn't really study since I was so drained from the 7 test.
After I studied a few days for the 63 it was a piece of cake.
I have 6 and 63 - my best advice is on the 63 is just apply COMMON SENSE to most of the questions and you will do fine. The 6 you need to study harder for.
