Can Khan Academy help me get a 1480++ on the new SAT?

Hi all
I am a rising junior spending part of my summer studying for the SAT. I took the PSAT in the fall and got a weak score of 1160/1520 (no writing portion). I immediately plugged my scores into Khan Academy where I got personalized advice on my weak points from the last test. Since then, I have been doing atleast 40 questions a day, and on each topic (for example complex numbers) doing the 5 question mini quizzes over and over until I get considered mastery. I will complete 4 practice tests before I take the SAT in october. Do you think with this discipline, I would be able to improve my score to atleast a 1480 (32 ACT equivalent) on my SAT? Do you think it would be easier to self study the ACT? Should I just give up on Khan Academy and get a private tutor? Any advice given is appreciated. Thanks!

Since there is a limited question bank on Khan academy have you run out of questions by doing 40 questions a day since the fall? Does it repeat questions once you have exhausted all of the questions?

I’m only using Khan academy for the questions since you can never have enough questions especially official ones.

No harm in doing Khan Academy because you get extra instruction. But, you should be taking as many practice tests with a pencil and paper as you can. Practice sections with a timer. Make sure you take several complete tests all the way through. Review what you get wrong. Learn the material. Study vocabulary. Practice more, pencil to paper.

cerealguy3, we took the PSAT in may so I just started doing practice in june. I’ve done a lot of practice so far and haven’t seen any repeats yet.
