Best/most accurate practice SAT tests (2016)

I’m trying to find the best practice SAT tests, since College Board seems to have a very specific way of making questions, I heard most prep book companies have practice tests that are not good representations of how the actual tests are. I am currently using Khan Academy’s quizzes and practice sets but the only full length tests released by College Board are the four on their website. I am trying to raise my score by 150-200 points and I find that practice sets are really helpful to me. Do any of you know what test resources reflect the College Board type questions the most accurately?

Khan Academy has official questions

I’m in the same boat as you. I have heard Kallis SAT is good.
