So by my senior year I’ll have a 3.5 GPA. Between my junior and senior year I’ll have a total of 15 AP classes taken I’m taking 7 AP tests, 3/4 Sat subject tests. Get a 1400 on my SAT the new test out of 1600. I’ll be president of 4 clubs and captain of my tennis team. I also volunteer as an EMT and numerous other places. My brother is an Ivy League graduate I do not want to mention which school but what are my chances of getting into the same ivy with alumni status if my GPA is low like a 3.5
Quite honestly really slim and with your information hard to tell if your ec can really help you. But based on the numbers your odds are close to zero
