I REALLY want to apply to UPenn. I have a high SAT score (in the 1500s) but I have no subject tests. What do I do?
I think the subject tests are optional at uPenn. Do you you have a high GPA with tough (AP) courses? Do you have good recommendations? Can you write a good essay? Finally, are you accomplished/passionate about something outside of academics? If you can answer yes to most all of these questions, then you should apply.
Rest of your app? Why do you want to apply to UPenn?
