Increasing the SAT score

I’ll be going into my 12 grade this year. Well i took the Dec sat and scored 1760 followed by the Jan sat in which I scored 2070. Now during my preparation for my Jan sat I’ve solved the blue book, Princeton review, barrons and some previous years papers. I’ll be taking my sat in June now, so how can I further improve my sat score without enrolling into any course?

around 100 to 200 points if you try hard enough

Keep in mind that the June SAT is the new one, with a new scale out of 1600 and the optional essay.

Okay so what materials do you guys advise me to study taking into consideration the books I’ve already solved and my disinclination towards joining an online course?

CollegeBoard has released 4 full practice tests for the New SAT. You can find them here. https://collegereadiness.collegeboard.org/sat/practice/full-length-practice-tests
They also have a new official study guide, kind of like a blue book for the new SAT with 4 tests as well, but I don’t know if these tests are the same as the ones on the website.
