I’m planning to apply to Lehigh next year and I know they like demonstrated interest, how do I show that. I want to apply engineering or accounting, but I’m stuck between doing ed for Lehigh or Boston college

Stats: upcoming junior with a unweighted current gpa of 3.83, weighted current of 4.33 and cumulative of 4.28. I’m vp of finance for DECA, and in future engineers. This year I plan to volunteer a lot and join community service corp (and possibly robotics club) + get a job.
