You are VERY fortunate, @college2k17md . You have two good and very different options in CatholicU and UMd, both of which you can afford thanks to your parents. The fact that they are very different means you get your choice of the type of school, and location, you will attend.
Add to that that you will not have to borrow money to make them affordable.
Visit both. Look at their programs (UMd engineering I would think is stronger but that is only part of ‘fit’…sit in on a class, meet some students and professors). Spend time on both campuses and see what the Honors Programs get you at each.
Then count your blessings and choose. You are a lucky kid.Don’t lose sight of that.
