Merit Scholarships Received by Incoming Class of 2021

My DS didn’t receive any merit based aid from Lehigh, but he got 1/2 scholarships to RPI and UConn Honors College. He’s dying to go to Lehigh (accepted to Mechanical Engineering), so we are considering appealing. Has anyone else done this and succeeded? What was your experience appealing Merit aid and did you succeed?
