My skill level for SAT math doesn't go up

Hi! I've been using Khan Academy for SAT practice for a while now, so in math, I have practically every topic on level 4 except for Right Triangle Trigonometry, which I have on level 1. Even if I get every question right multiple times in a row the level won't go up, and I don't know what to do :/ 

I really don't care about the level, but since the material gets harder as you go through the levels I'd like to see the questions lol

Is there something I'm missing? Any help is welcome :)
