Personally, the difference between 1500 and 1550 is marginal, and the time you’ll need to put in could be used for other things like college apps. Are you going to an english/reading related major? If you’re going to a STEM field, an 800 Math score will make up for your lower reading score.
I got a 1550 on my SAT, but with the Test optional policies this year it feels worthless so I don’t think you need to work more on your SAT.
