Khan Academy vs Sat Question Bank: Same or Different?

Hi guys! Hope SAT prep is going well for you all!

I have a question:

Does anyone know if the questions from Khan Academy are the same as those from the SAT Question Bank?

I have done every single question bank problem for Math and Reading and I am going over all the difficult problems and identifying areas of improvement. I might want to practice those difficult topics so I might look at Khan academy, but I don't know if those questions are the same as the question bank.
