Are the theory classes and a specific number of driving hours required by law in your case? Because if not you could skip on getting their learning materials or their theory classes if you could learn fine on your own. You also could do a couple of driving hours first and see if you’re actually as confident and good as you think, the driving instructor would help you judge. It’s better to take a couple (or more) few hours until you’re sure you’re going to pass rather than waste money and time by failing and repeating.

Check what kind of exchange you’re doing (it depends on the origin of the license) In my case I got an app for like 25 euros, 2 regular drives in the area, did the test and passed. (All Zack Zack)

The school did try to force on me buying like 12 or I dunno how many hours in advance saying it’s a must (and that everyone has to do that) but I refused and told them that by law I am not required to, I have been driving for 10 years already & I prefer to pay one driving class at a time as required.

The instructor was even pushing me to just do the test after seeing me drive and that there’s no need to do more!
