It's a license to learn in my opinion. This is a very deep and wide hobby / service.
To get the most out of it, you need to learn considerate operating habits, and know a little tech.
The question of hard or not doesn't really track for me. Surgery or a law license would be hard for me, since I have no prior training. If you have a tech background, you may see it as easy. I have seen determined people have to give it a few tries. There is a fair bit of memorizing on each of the three tests. The laws and regulations are not a thing you need to understand, just know.
