Back in the 80s the books i found easiest to learn from were the Radio Shack ham books.
It gave you the question, had the 4 possible answers, then a short paragraph on the why of the answer.
Sadly Radio Shack changed their business model and are no more.
I was active during the 70 and 80s but let my general license lapse in 2011. I was a CW freak from my Army radio days. I have always kept a 2meter/440 mobile on hand in case of emergency. It was a great hobby.
