The CW test scoring is as follows:
You copy 5 minutes of code (vvv vvv DOESN'T count...)
Then you answer a 10 question fill-in the blank question (not multiple choice).
Questions might include:
What type of rig?
What type of ant?
Names/QTH on each end, etc., so just "whatever de whatever" won't get it.
Tip: If you copy "california" DON'T put down "CA". Write down on the exam paper what you heard.
If you don't pass the 10 questions, then the examiner(s) may look at your copy to see if they can find 1 solid minute (25 chars) of correct copy. I know this one personally, as I passed my CW element with 26 chars
Good luck es 73 de
