Thanks for all the inputs that I have received till now. Lets keep the the tricky point of 4.0 GPA aside. My dad is realistic, a good listener and will be objective when it really matters. Whatever he is saying is more likely to motivate me, than to find a reason not to pay. Does Purdue has any great advantage like better research labs, ability for students to get more internships, more aerospace companies coming on campus to recruit aerospace engineers etc. Any thought on that will be much appreciated. Thanks.
