Is Notre Dame right for me?

<p>Hello everyone I am an international student who got admitted to ND through EA.However, I am not sure if ND is the right choice for me and I should apply for other schools through RD or not. I went to a Catholic all girl high school on a foreign exchange program during my junior year and I loved the friendly atmosphere. I've heard so much about the incredible community and school spirit ND has and I am definitely drawn to that. But i have a few questions to ask. I hope you would have the patience to help me!
1. What is the theology requirement like? Do we have to take it every school year? How much is the workload?
2. In America, I got along with the girls and didn't feel much like a foreigner. How is the social scene of foreign students like in ND?
3. I know this is cliche but as a non Christian, I still want to ask about the issue of religion. How present is Catholicism in ND? Because in the school I attended in US, most were Catholics but a lot people weren't really that religious. Are there students with other religions rather than Christianity in ND? I consider myself a Buddhist, but Buddhism is not a religion technically.
4.I am pretty sure I want to study economics and then go to grad school. Is ND going to prepare me fully for a good business school? If I choose a different school for grad school, is the alum connection of ND still going to work?
5.I prefer small classes and I wonder what is the usual class size in ND? Are the classes all taught by professors? How accessible are the teachers?
Thank you for your time and consideration!</p>
