its my first time so i dont really know whats gonna happen
Depends on country and also massively depends on the instructor guy. At least here you just drive for 45mins around the town. It has mandatory parking and highway parts, and rest depends on where you drive like here the route usually has one-way section and roundabout. Its pretty much the same to normal driving class but they usually want to bust you and might put you in tricky situations. Also some instructors are just ass and will try their best to fail you, while others might let you pass even though they could have failed you. Overall just drive bit under speed limit, keep safe distance to other cars, check your blind spot well and visibly, stay calm and don't ask questions and act confident.
