I was ticketed for underage possession and have prior tickets on my record?

I was ticketed for underage possession for alcohol and littering the other day. I was walking down the street with a bottle of alcohol, the next thing I know I was getting a ticket. I am 20 years old and in college. I have been in trouble before and have 1 underage possession ticket on my record already and have had a disorderly conduct expunged. I was just wondering what is most likely to happen to me? Will this affect me if I apply to law school? Jobs? What should my next move be?
