Mission 1400 helped me understand the math topics that I have been struggling with in a way that has personally been very informative and useful. The resources that mission 1400 provides definitely covers all of the sat questions even providing plans that help u find out what level you're at and what your next steps are which was really useful to me. I only wish that i had found this resource sooner instead of starting from basics this resource helped me improve on what i already know.👍👍
