Joy -
Purdue’s page says they have continual application processing. They moved away from rolling admission more than 5 cycles ago. The EA deadline is typically 11/1 and RD is 1/15.
Purdue is back to test required next cycle.
I also think it would be helpful to indicate that the college admits by college/major and some are much, much more competitive than the overall acceptance rate for the university. Same is true for the average GPA and test scores.
