Well, I got around the score that you're aiming for, but I don't know if I can impart any particular words of wisdom. I'll try, I suppose...
What I did (and it worked for me) was memorizing tons and tons of vocab. Like, thousands of words. I obviously didn't memorize the exact definitions, but I based it more on basic definitions. For example, "I remember 'dearth' as having not a lot, so maybe it means 'scarcity' or not having enough". The verbal section is a pain in the butt. I never could get out of the low- to mid-700's in the verbal section, no matter how many freaking words I memorized, while my writing and math scores were good

lol sorry, ranting.
Anyway, yeah, memorize lots of words and possibly study latin roots. For example, knowing bene- is "good" and mal- is "bad" can help a lot, especially if you're stuck between a few answer choices and you don't know the exact definitions. As for the math and writing sections...math, just try practice problems. After a while, a lot of them are kind of similar to each other. The math section really isn't bad if you have a strong mathematical background in algebra, geometry, and algebra II. Writing... I don't know about advice, but just read up on grammar books, I suppose. Make sure you know which preposition goes with which type of phrase. And never put "a" after "kind of". That always tripped me up
