Preparation for SATs

Hello,

I am currently preparing to write SATs next month but I'm in need of assistance. Most of the topics here at an advanced level which I have not learnt yet so doing practice does not really benefit me as it should. I have tried to search for some of the topics listed in the SAT dashboard but have found no lessons specific to my search. Is there somewhere I can learn these topics first before I start practicing?

For future notice, I think it will best if Khan Academy provided lessons and practice together to make learning easier for all students.

Thanks
