Congratulations on scoring a 750. That's a great score, in the 96th percentile! It means you've got mastery of all the main subject areas. In order to get the last couple of points up to 800, look at the minor areas - are you comfortable in trigonometry? How about statistics? The SAT's more qualitative statistics questions can often throw people for a loop. Geometry is also an area that often makes the difference between almost perfect and perfect scores. You may want to practice particularly tricky geometry problems, as these often show up at the end of the grin-in section.
Assuming you're comfortable with all these areas, though, that leaves reading, discipline, and stamina as the paths to improvement. The dirty little secret of the SAT Math section is that reading comprehension is almost as important as math skills. Many of the word problems have twists in them, so make sure you understand what they're asking. Similarly, many questions can ask you for a different answer than you'd expect. Paying attention to these will help you avoid traps. It's important to be disciplined in reading, and disciplined in solving. Follow a disciplined process no matter how easy or hard a question is, and always write out your work. This will help you avoid traps.
Finally, stamina. The SAT is a long test, and the Math sections have the most difficult questions at the end. Make sure to practice for sustained stretches of time, so you're used t taking long tests and being sharp at the end. Bring granola bars, apple slices, and other slow-energy-releasing snacks with you on test day... you don't want to have an immediate high and then crash. Building the stamina to stay disciplined for 3+ hours is difficult, but this can be the difference between 750 and 800.
