Do most students and parents consider difficulty of declaring/changing major?

@ucbalumnus "Wisconsin engineering frosh are initially admitted to a first year engineering program and must meet specified GPAs to enter their majors. For chemical engineering, students need a 3.5 GPA in their math and science prerequisites, and a 3.0 GPA overall:

Thank you very much for that, UCB.

My next question is how achievable a 3.5 in math and science courses is at Wisconsin. I think it makes a big difference whether it is 80% of Wisconsin engineering frosh that achieve a 3.5 and get admitted to engineering, or only 20%.
