Sorry to hear about that JJ

Definitely don't give up!
My recommendation would be one of the following:
1) Instead of studying online, pick up a study manual. I had good success (back in 1994) with the
Gordon West WB6NOA Technician manual. He does a good job of not only giving the correct answer, but an explanation of
why each answer is correct. One note: I have never tried the online study courses, so they may be as good as the study manuals, I'm not sure.
2) Supplement your online studying with the
ARRL Handbook. It should be a staple item in every ham's shack and is a fountain of knowledge and reference material.
3) I'm not sure how the online study courses work, but I know you can take practice exams on QRZ.com. Take as many as you need for free, and it will be a good way to gauge how ready you are.
Again, keep on studying and don't give up! Good luck on round two!
