How do I improve my score???

I scored a 1110 on my PSAT, which is the 80% . I want to hit the 90-99%. I didn’t study or prepare because I wanted to see how’d I do, I also haven’t taken algebra yet. My highest was reading comprehension (30/38), 2nd lowest math (27.5/38). And the worst was writing and language (26/38). How do I raise them??? Any links or book names and tips will be well appreciated

@courtz215 I recommend my students Barron’s 2400. I think it is good for practicing Math.
