I think it is much easier than most people realize.
Went to a conference. Wife read sample questions to me while I drove. About an hour and a half drive.
Next morning, flipped through the book for about 15 minutes. Sat for test. We both passed. I finished Tech element first, so I flipped through the General class book for about 20 minutes and then took the General test. Passed.
Still ahve to take Morse. That kills me, despite being only 5 WPM.
If you've taken a high school physics class in the last 30 years, you could probably walk in to the technician test with zero prep and bumble your way to a 70%, no reading, no studying. If more than 30 years ago that you took High School physics, bet on an 80% since more of your H.S. curriculum would have been on related materials.
