Meaning no disrespect sir, your mistake was putting the cart before the horse in your haste. You would have been much better informed had you obtained one of several available study manuals and still you could have aced the test. It's simple, for example the Gordon West manuals available from the W5YI Group are IMO the best, highlight the correct answer given in the text (with explanation) and memorize only the questions and the correct answers.
Since you have considerable catching up to do I suggest locating and joining a club in your area where you may meet with established hams and discuss so many things. All your questions are best answered in person so immediate explanation and discussion may be had. You'll have to anyway since those having accredited VE sessions are where you'll take the test so you may as well join up and take advantage of all they have to offer.
"Oh, by the way, I also have a Gen. Radiotelephone Operator License, since 1967."
How so? The GROL did not exist in 1967 but rather Radiotelephone 1, 2 and 3 with endorsements, same for Radiotelegraph and Radar. Now fess up, you had at least a 'phone 2 and were grandfathered. (;->) I'll give you one thing, since you know theory and the math behind it taking the test should be a snap, all you need to learn are the band assignments and CW if you want to operate HF above 10M. Not only that you already know more than some hams will ever learn in a lifetime, congratulations.
