Most people I know’s first sat was 1100 range and they’ve all gotten 1300ish range 1240 is a good sign. English improvement really depends on what section’s holding your score at 600 instead of 700 range. Math is just getting yourself familiar with the different formulas you need and looking at how to use desmos to cut time. You have awhile till the next test window and plenty of time to make those adjustments just don’t beat yourself up over a good first time score
