I am a seniorYou’re taking pre-calc right now? Are you a senior? There might be a couple of math concepts on the SAT that you haven’t covered in school yet. I strongly suggest going through the entire Khan academy math SAT prep curriculum. You don’t need to just review—you need to learn some new concepts/formulas.
If you’re a junior, then you’ve got plenty of time to learn and prepare so no worries. Definitely make it a priority to increase your score though
