Since your GPA is weighted you currently have around a 3.8ish Weighted which really is just not high enough for Wharton. I would try both the new and old SAT. I hate the writing section of the sat though so I would probably prefer the new (even though most schools don’t even consider writing). Its up to your preference. What is the average GPA at your school? Is a 3.8 W high? At my school that is below average for the top students.
