I think you have a great shot, although all the Ivies are reaches. If you can afford the cost of attendance, apply early decision/REA for your most fave Ivy.
Your activities are great but make sure they show up in a way that showcases your strengths, who you are, and why you’re a fit for the college and vice versa.
To be candid, your weighted is great, but unweighted may put you in the borderline basket. I only say that because I’ve seen students and CVs that are just as impressive if not more impressive than yours with higher stats but still get WL or rejected. 3.8 flat may be low but if you have a strong ACT, it could put the AO mind at ease. My son’s ECs were well rounded and strong but def not at national recognition level as some of your activities. I think his essays and LORs, as well as his 36 ACT helped him to get over the AO objections. His W GPA was excellent but his UW was almost 3.9, but not quite. I always thought that was his Achilles heel. When I looked at Ivies and schools like UCLA and the stat the kids post. It always seems like a 3.9 UW is the magic cut off. Kids who have a 3.85-3.89 seem to have to work much harder to convince AOs—in forms of test scores, rigor, ECs, LORs, as well as applying ED, which shows them that they’d help the yield curve.
With places opening soon for testing, see if you can get a couple rounds of ACT tests in to lock in a solid score. Don’t leave anything on the table if you get a chance to take the exam. Don’t give the AOs reasons to question your unweighted GPA. Good luck!
