How to improve sat score by 100 points

<p>Hi, I’m a sophomore and I recently took a practice SAT and only got a 2025. I didn’t take it too seriously so I think I can do better. I know the ivy league average is around 100 points higher. Does anyone have any tips on improving my score?</p>

<p>If it helps my separate scores were:
Math: 640
Reading: 670
Writing: 715</p>
