Question for young American people?

This question is mostly for high school or college students in the U.S.

1. Do you guys really party a lot? ( i know i have watched too many American movies)

2. Do people normally get together at someone’s house that is big when it’s a huge party?

3. At a huge party, normally a half of the people are guys and the rest are girls? like half and half?

4. Is it a must to bring alcohol for the party you got invited?

5. What’s something people normally do at a party besides just talking and drinking?

Thanks in advance!
