Have you filed your FAFSA yet?
Priority deadlines for financial aid are coming up quickly. tOSU’s is February 1. You need to submit even if you have not yet received a decision from them.
Do you know what your FAFSA EFC is?
Why did you apply to Ohio State? If it is because you have family/friends or other support in the central Ohio area you might consider Otterbein Univesity. https://www.otterbein.edu/engineering/ It is a small newer department, but Otterbein students are well thought of and they offer decent financial aid. They are in Westerville (a separate municipality from Columbus, but still connected via local bus routes). https://www.otterbein.edu/financial-aid/financial-aid-estimator/
