Tips for driving test in Norrtälje?

Hi,
I will have driving test at Norrtälje this Thursday. I took 10 driving lessons and I have driving experience over 10 years in a Non-EU country. I failed at Upplands Väsby twice. The reasons are mostly adapting my speed to the road such as going to low at 30 road or merging with lower speed to high speed road. Now I want try different place. Any suggestions?
