Can I learn driving theory in 3 days?

Moved to Learning to drive.

I crammed 3 days before mine and got 49/50. just spam the app and literally the same questions come up.

I had a similar experience - but of course different people may need more time, whereas others may be able to pass in less time. I took my test today with barely 2 days of revision spent on it, and passed the multiple choice section with 47/50 marks. Just use the DVSA Theory Test app if you can and constantly do mock tests - you'll definitely see a rise in your average score the more you do it (the first mock test I took on the 1st of May failed badly with getting 36/50, but today before the exam I didn't get anything lower than 47/50, it's just a matter of memorising the answers - the same questions did come up in the real thing for me). Another tip is to try not settle with getting barely a pass, as in aiming for only 43 marks. If you're just getting 43/50 consistently in your mocks then you could end up feeling a bit annoyed if you end up getting 42/50 in the real thing. Basically I wouldn't say you're being naive like you said; if you are really that keen then I'm sure you'll do fine. It really is a lot of common sense, just do mock tests and find out what you don't know then learn it and repeat. Good luck.

tried that the first time and got 38/50... second I got 42/50, now defo downloading the app don't wanna be too confident

I learnt from a theory app, used it every day for a month, about 5 mins a day. I passed first time on the theory. Every day solid for a two weeks I think is minimum. Three days, it's too much to take in, and not enough time to make some mistakes.
