Can I increase 400 points in a little over a month?

Hey. I’m currently preping for the SAT exam and I am having a mental breakdown. I am becoming grade 11 this summer and I have always been an outstanding student in school; I took bunch of grade 11&12 courses and received 94% avg. in all courses. I also took the SAT ll Math ll this spring and received 750. So, I thought I was set for the SAT I exam and I took one of the Baron’s practice exam with ease. But, when I received my score, I was shocked because I had a score of 1770. My original plan was to get 2250 or higher on the SAT practice test by the end of August and ace this Fall’s SAT exam. But, after taking this practice exam, I realized that I am missing 480 points. I got

Math: 640/800
Writing: 570/800
Reading 560/800

I think I can raise my Math score up to 760, but I don’t know how I’ll raise 360 points on Writing & Reading sections. I am preping the SAT with the blue book, SAT Barron’s book, Erica L. Meltzer’s grammar book, and Barron’s SAT Vocab lists, but I am not sure how to study with all these materials. I am also planning on buying the Direct Hits series this week, but while I’m also prepping for the SAT ll Physics & AP Calculus, I can barely manage to spare 3 hrs a day to study for the SAT l. So, can you please help me with coming up with a study plan or a guide that I can follow to achieve my goal? I am desperately in need of help! Also, can you help me how I can write manage my time well during the Essay section? I can never finish my essay in time; I usually get to the end of writing my Second Body paragraph.
I am really frustrated right now and I’m running out of time. Please help!!!

“I also took the SAT ll Math ll this spring and received 750. So, I thought I was set for the SAT I exam …”

You do realize the difference between SAT and SAT II tests, in terms of what they test, don’t you?

Yes, I do understand. I made such a statement because SAT I math is way easier than the SAT ll Math ll. The point I wanted to make was that because I had an okay score on the SAT ll math ll exam, I believed that the math sections on the SAT I would not be a problem for me.

The SAT I is an aptitude test and the SAT II is a test of achievement.

400 point incr in only one mo is unlikely. It is especially hard to bring up the CR score. CR skill is something that takes years to build, unlike M where u can memorize a few equations.

What if I have approximately 2 months to study for it?

@Fly1567 Nothing is impossible , Just Practice too much and review your mistakes !

Yes you probably can if you work hard
