Compare/contrast my ChemE programs

Can your afford the cost without more debt than the federal direct loans?

Have you applied to in-state public universities?

Out of the schools you named, UIUC and Wisconsin have direct admission to the major. UIUC requires a 2.5 college GPA every semester to stay in the major (see http://chbe.illinois.edu/wp-content/uploads/2017/07/CHBE-Advising-Manual-2017-2018-combined.pdf page 13). Wisconsin requires a 3.5 technical and 3.0 overall college GPA to progress from frosh to soph year ( https://www.engr.wisc.edu/academics/student-services/academic-advising/first-year-undergraduate-students/progression-requirements/ ).

Texas A&M, Minnesota, and Purdue have first year engineering programs, followed by competitive admission to major. They do have assured admission college GPAs (3.5 at Texas A&M, 3.2 at Minnesota and Purdue). More information at the following:

Remember, earning a 3.5 GPA in college is typically much more difficult than earning a 3.5 GPA in high school. Some colleges’ grade distributions by course are listed at http://talk.qa.collegeconfidential.com/pre-med-topics/2074436-some-colleges-have-grade-distribution-information-available-by-course.html . So be aware of the risk of being “weeded out” due to departmental capacity limitations at each school.
