I just took the test today. I haven’t taken any driving school classes. I’ve been driving for 14 years in the US before moving here.
This site’s questions are SO much harder than what’s actually on the real theory test. The questions are much more similar to the ones at elevcentralen.se, however You learn a lot of very valuable information from the tests here at korkortonline.se. If you can, use both. The app for elevcentralen.se is really nice because if you do the custom tests (similar to how you do here) you have a bit more customization, and they show the answer right away so it’s still fresh with you (instead of having to go back and look through all results at once to recall)
Take your time, study, you can do it!
