I want to know the middle 50% range for SMU, Tulane, and Vanderbilt, but I can only find information on the range for each individual section. If anyone knows the middle 50% for composite scores, please let me know. Thanks! 
Tulane’s middle SAT range for the class of 2021 is 1410-1500 and its middle ACT range is 31-34.
The Common Data set format is to report the SAT scores separately. So that’s how many schools report the data. If you add the reading and math scores on your own, you’ll get pretty close (but not exact).
Here’s data for Vandy 2021:
Old SAT**
Middle 50% Critical Reading: 740-800
Middle 50% Math: 770-800
New SAT**
Middle 50% Evidence Based Reading and Writing: 710-770
Middle 50% Math: 720-800
Middle 50% ACT: 33-35
