I passed my automatic driving test on October 15th after four tries (including this one) in Farsta.
There were a lot of factors at play and I have no experience doing the test anywhere else, but I can confirm that that area poses a lot of challenges. My impression is that roads in Sweden are already fairly complicated, so I would recommend practicing A LOT with an instructor who knows the area and perhaps trying a new area if you fail.
I passed after receiving classes with Petter from Jarla Odenplan and can recommend him to those who perform well with a calm and experienced teacher.
Good luck!
