I recently made a website that has video answers and explanations for all 1,232 questions that are on the 8 released College Board tests. The site is:
All of the courses are free.
A bit about myself: after getting a degree in math from Yale, one of my jobs has been to tutor students for the SAT. I've personally tutored over 700 students for the redesigned SAT since January of 2016. I made these video explanations so I wouldn't have to keep explaining the same concepts over and over again to my students. It's my hope that the people on this subreddit will find these videos useful.
Let me know what you think about the material.
