Luckily for me driving here is mostly the same as in Austria, just a bunch of small differences. I recommend downloading a drivers test app on your phone (mine on android is literally called 'Drivers Test'), on the one I got you can set the state you're in, do practice tests and it explains why the answer is right/wrong. I like studying by doing practice test questions, I did the same for the GED. I passed the road test too now, I only looked up youtube videos about what to expect and they explain it well, though obviously I've had a good amount of practice with 4 months of driving in the US.
