Hej, sorry that I write in English.
I suggest you search for a complete safety check video and make a checklist. You will be asked to check one thing or two randomly. I also recommend that you study how to switch lights (for example, fog light) in both Volvo and Volkswagen cars because they are very different in these cars and you don’t know which one you will drive there. Usually they just ask you to do something very simple, like honk

but better be prepared!
Safety checklist example:
Tires: Check pressure (including spare) and tread depth; look for damage.
Lights: Test headlights, high beams, turn signals, brake lights, hazards, and reverse lights.
Fluids: Verify levels for oil, coolant, brake fluid, power steering, and windshield washer fluid.
Brakes: Ensure they are responsive and don’t squeal/grind.
Wipers & Washer: Check blades for streaks and fluid reservoir.
Horn: Make sure it works.
Mirrors & Windows: Clean and undamaged.
Dashboard: Check gauges and warning lights.
Seatbelts: Ensure they latch and retract properly.
Hisingen examiners are nice. The routes could vary, but of course you will be driving around the area, on main road, railway crossing, roundabouts and the highway. All roads are relatively easy, except for the highway because there is a bus lane running in the most right lane. It’s a bit tricky to enter because of that.
There are some videos on youtube showing the route in Hisingen. Unfortunately Incannot post the link here due to restrictions from this site, but you can literally just search for this video: Uppkörning Hisingen Förarprov med tips och Kommentarer
Good luck!
