I have to say many seem to think you just drop in to your local GADO and pick up an A&P ticket.
The A&P written test is the hardest one the FAA administers, simply because it cover so many different subject areas, and not just airframes and power plants. It's actually three separate tests. A general knowledge test, then the airframe test, and finally the powerplant test. The closest other test I could imagine the FAA gives, that's tough, is the flight engineer's test, (do they even still do that one?) and this is that - but on steroids.
I went to Northrop University in Los Angeles to get my A&P ticket and it was an ordeal. And if you're older like I am now, start boning up on your math. You'll need for everything.
Here are the areas you'll be tested on:

The full course was 18 months and my G.I. Bill covered most of it, but I had to work in a Shakey's pizza parlor at night just so I could eat. And every lunch period I'd sit in the cockpit of an old Stearman they had there eating left over cold pizza and studying. And it really took me a long time before I could enjoy pizza again. (Years later I got to fly a Stearman and I had that landing sight picture ingrained in my head from all those lunches spent staring out that cockpit wind screen.)
Then if you pass the written exams, and many don't the first time, there is still the practical exam conducted by a DME, or whatever they are called nowadays, and essentially you spend a day (or sometimes two) in their hangar shop working for free and paying $250 (at that time) for the privilege. I timed magnetos, changed out some brake pads, removed a damaged aileron from a Cessna, did the sheet metal work to repair it, replaced it, and rigged it. And I enjoyed that one as the examiner and I took the aircraft around the patch to test it out.
So, if that's the hardest, what's the easiest written test? The Parachute rigger's certification is the easiest simply because it's the shortest one in terms of the possible question pool. And the entire question pool is small and easy to study. But, in both cases, or more probably all cases, these tickets count for little without real world experience. I was already a skydiving instructor when I got my rigger's ticket so it was all relatively easy for me.
One more thing about the A&P question pool. While the three tests are 50 questions for the General, then a 100 each for the other two - the possible question pool is enormous. So you really can't just cram study and pass - you've got to know the material.
I was already in my thirties when I started A&P school and I was the old man on campus. But, no mater your age, if you have the drive, and the wherewithal, then by all means go for it. I'm in my seventies now, and still pilot friends call me begging for help with their airplanes. And I know if I wanted to drop out of being retired, I could go to work full time in just about any GA shop in my area. And an A&P ticket, unlike some others, is good for life. (As long as you keep your hand in occasionally like I do now.) And unlike pilots - the FAA will graciously allow you to die with a wrench in your hand carrying out the privileges of your ticket.
