Adding A Upper and Middle Level SSAT Course

I have been using the SAT platform to prep for the Upper Level SSAT Math and Reading Parts. One, I would love for there to be a vocab for the SAT, just in case some people don't understand the words. Two, An SSAT platform on Khan would be helpful because it is hard to find an free practice site for Middle and Upper Level.

Thank You,
