I scrapped kungsholmen since you'll need to live in stockholm to get in there. Mikael elias is also on my list. But a bit down. And I will get accepted into the school over - Värmdö Gymnasium, also a very good school. Located not in värmdö but in gullmarsplan.
I also have nacka na-na last. It's failsafe. Btw, one my best friends had 320 points when after the ninth grade. She chose nacka na-na, blaming on her lack of fantasy. (It's like if you can choose to go in any school that exists, and join one that's very easy to get into. (stupid)
