Hello. I’m upgrading my licenses to 100 ton to 500 ton. I got a letter in the mail approved to test. I know I have a year to test and when I take my first test I have 3 mounts
to take all of them. I wanted to know if there are some really good study aids, ie some book so I can read and understand what I’m testing for, and not just q and a stuff.
thank you for your time.
