Hi there, and congrats for getting this far with getting your driver's license!
Best advice I can give for folks trying to focus on practicing for their driving tests is to nail the basics of driving... parallel parking, stopping smoothly, lane changes, and observing traffic signs.
On test day itself, most DMV examiners are there to assess whether you're able to follow the rules of the road, use your mirrors properly, and drive safely. Do all that, and you're guaranteed to pass!
Stay calm, drive safe, and best of luck to you, friend!
