Sorry I can’t provide any guidance on your chances given that you just finished sophomore year and haven’t taken the SAT’s. You still have two more years of high school to complete. Please disregard any advice I have given because I was under the impression that you were going to be a senior in high school getting ready to apply ED to UPenn. You did not mention that you just finished sophomore year in your original post. Perhaps other posters will have more knowledge to guide you. Best of luck.
