MIT or UMD full ride? Chemical Engineering intended major

Okay, I’m going to continue to apply to scholarships and I’m going to write up an email to my financial aid counselor to try to work something out with her. Do any of you have any resources or websites that have good advice on writing up an email to try and work out a better fin aid offer? Should I take a screenshot of what Yale and UMD are offering me and include it in my email?
