Just back from Intro to Computing Dante. I would say 10% is exactly like the Peterson's test, another 40% or so is the info you learn from the Peterson's test. Now, the other 50%, Nothing like the Peterson's, but about 30% common knowledge if you can get around the obscure questioning and the other 20% I had never heard of. That all being said I did pull out a 443 even though I was sweating the results. Thank you for all the good luck and help.
