What would I have to do to get into TAMS?

Hey, I’m an eighth grader who really wants to try for TAMS and I just wanted to know what I have to do (like courses or extracurriculars) that would help me to get in. I got recognized for the Duke TIP Talent Search in 7th grade and I scored a 1210 on the SAT (I know its not that much, but I didn’t really have time to study…). I’m currently in NJHS (National Junior Honor Society) and NJAHS (National Junior Art Society) and I’m taking Algebra 1 right now and I’m planning to double up on my math courses (by taking Geometry and Algebra 2) in my freshman year. By doing that, I can take pre-cal during my sophomore year. And so far I’ve gotten really good grades and I’ve gotten A Honor Roll the past two years. I know it really kind of depends on my grades and GPA in high school, but what else can I do?

Thank you!
