That's how I studied for my exams:

1. Read through (and understand) West's book. 2. Go to qrz.com and take the practice tests until I could pass with a 95% multiple times in a row, and I had answered every question in the test database correctly at least once. You only need 85% to pass the real exam but I wanted a margin of error.

I passed my tech, general, and extra exams on my first tries. That's the most prepared I've been for a test in decades.
