<p>Each school has a different grading system. Your school’s naviance data would be a better reference if it has a sufficient sample size. You should use that 3.91/1948 as a reference for your chance. I would not count on the 17/34 acceptance rate as you don’t have the stat of the rejected students. Again, your school’s naviance data verify that you are a high match to WISC as your GPA is below the average while your SAT is right at the average. Remember, the sample size of 17 is not very big and the standard deviation can be very large. Also, this assumes you have comparable EC, essays, and recommendations.</p>
