yes, they are harder to get.
When I got my drivers license, I had to have 16 hours of driving lessons, and I believe just as many theory lessons and I think that number has gone up. It cost around 2500$ to get the license 20 years ago and I didn't fail a test, not the official test or the ones the driving school had.
Then I had to go to the written test and then the actual driving test(I did end up having 4 extra driving hours because there was a shortage of police officers to take the driving test with me, so I had to wait 1 month and needed to keep the few skills I had fresh in my mind). The written test was kind of like multiple choice where you saw a picture and then should tick off anything from 1 to 5 things. Some of them were really hard because you had to know what they wanted to tell you with that crappy picture, like ,oh, I have to be aware that the road turns, but not the cyclist in this case because he is on a bike lane separated by grass. and then 5 pictures later I have to be aware of the cyclist because the bike lane was not separated by anything but a white line and iirc they called that "the equipment of the road" that I had to be aware of, which also sounded weird before translation. :)
And they had their trick questions too. In none of the pictures it was OK to use the horn. :D
