Practical driving test (driving test)

Hello,
I am going to take the Practical driving test (driving test). The exam fee is 1600 sek. I saw ın some websites mentioned to be 800 sek. Why there is such a difference?

Also can I use my own car in the exam?

Thank you.

I think;

The trafikverket fee is 800 SEK + Renting their car is 800 SEK.

If you bring a car I think you still have to pay 800 SEK trafikverket fee. But please check there are certain requirements for bringing your car. (Dual controls etc; a car from driving school would work)
