How do I add my PSAT score into Khan academy and how do I connect my Khan account to Collage Board

I had heard there was a way there was a way to add your score to Khan in order to get a personalized study course. I am unable to locate how to do so.

I also know you can connect your collage board account and khan account, however, how to do so is unknown to me, as everything I try does not work.

ANY help is very much appreciated.
