SAT Practice sections

I encourage you to do the practice SAT tests. They are similar to the real SAT and will give you your score immediately after you complete it. You can work on your speed by completing the practice test in 4 hours. https://www.khanacademy.org/mission/sat/exams 

I wouldn't do more here. If you have an absolute 100 % in every single thing here at KA, I would just move on to official SAT practices or buy some book.
