Driving theory? I spent a week studying for it. I just bought an app 'Driving Theory Test 2022', and I did those mock tests you can find online.
Like 45+/50 questions on my actual test were familiar to me/I had done before, so I found it easy to get 49/50.
Practice hazard perception as well, I think there are a few more options to do that nowadays..., I did mine back in 2016
