I had some trouble learning the theoretical part. My driving instructor did this thing once a week where you could go and do mock tests. That’s how i learned it, i passes with 0 mistakes at the end.

The other thing that helps but i also realised late was to look for real life examples. Like if the question involves a roundabout, think about a roundabout that you know or use and think about what you would do there. Somehow the pictures didn’t do it for me. I helped a friend passing his test by driving him around and showing him real life examples of his book.

But to answer the real question, having a licence is probably always good, but if you never drive, you just never get a routine and you are suddenly the danerous guy on the road.
