What would the Texas A&M price be if you do not get the NMF scholarship?
Note that Ohio State and Texas A&M admit to a pre-engineering program, and you must later apply to your desired major, using college grades and GPA in prerequisites for your desired major. (Be sure that you are in the engineering division, not admitted to a non-engineering status from where it may be more difficult to switch into any major in the engineering division.)
Ohio State: need 3.2 technical / 3.0 overall, or 2.0 technical / 3.2 overall for CS; need 3.2 overall, or 2.9 technical and 2.0 overall for ECE. https://advising.engineering.osu.edu/current-students/applying-your-major and https://advising.engineering.osu.edu/sites/advising.engineering.osu.edu/files/uploads/Admission_To_Major/engineering_major_application_information_su2018-sp2019.pdf
Texas A&M: 3.5 assures admission to your desired major, otherwise need to apply with GPA and essays, ranking at least three majors. https://engineering.tamu.edu/academics/advisors-procedures/entry-to-a-major/application-preview and https://engineering.tamu.edu/academics/advisors-procedures/entry-to-a-major/resources/analysis-spring-2017-admission-cycle
On the other hand, UIUC with direct admission to CS would be a high extra price to pay to avoid uncertainty about getting into your major (if you were admitted to UIUC without direct admission to CS, chances of getting into the CS major are very low, so do not bother, especially at the higher price).
Do you have any other admissions, including net prices and whether you have direct admission to CS or if CS is non-competitive at that school?
