@chris1229 Clemson does admit by major. You elect a first and a second choice on the initial application. Contact the department to see how he stacks up. Everyone is so helpful and candid when we have called to ask anything. Tell them his test scores and ask them how they compare. Stats for engineering are sometimes higher (spends on the pool of applicants), however, there are also a lot more students admitted into the engineering major than others.
And just so you know, the initial Clemson application is very simple - no essays, no letters of rec or anything. The Honors college application is completely separate and consists of several essays and letters of rec.
All the best to you. Your son’s GPA and class rank are impressive. Congrats to him!
