<p>Don't worry, you don't need to know what you want to study right now, and if you do then good for you though it really isn't important and plenty of college students enter their freshman year undecided so you definitely have enough time to really consider it. Though if you know what you want then good for you.</p>
<p>As to commuting, i guess you bring this up b/c the colleges you are considering are in the near area, hmm though I think if you have travel more than half an hour or more than 45 minutes I think it's too much and the gas money could very well compensate for room and board, but it all depends. </p>
<p>You can get more than one outside scholarship, that's for sure, any plenty of schools which focus on merit aid will give multiple scholarships, so look into the colleges in question and apply for outside scholarships.</p>
<p>Financial aid basically depends on your family's income, b/c if you can pay then you will be paying, so... Though colleges that give merit can get you plenty of money with good scores and rank, so...</p>
