What GPA would give me a really good chance of getting in? Does anyone know the average?
You can see that info and more if you Google “Duke Common Data Set”.
You need to approach high school looking to do your absolute BEST. Forget about what Duke or any other school wants.
Absolute GPA doesn’t matter. Instead focus on take the most demanding courses you can and excelling. Shoot for top 1-2% of your class rank. This will lead to the highest possible rating for Academics and Achievement.
