I have my extracurriculars going for me, and my ACT score isn’t bad, but obviously my GPA is weighing me down. My essays are usually very well written. Which of those three majors would be the best choice for me to go with when applying to Purdue that I have a shot of getting into but also will have a good job prospect after graduation. Any help is appreciated! Thanks!

In my opinion you are a strong match for admission. Purdue would not be an academic safety for you nor is it a reach. I think you will find it more difficult to receive one of the universities scholarships.
