Hi Julisa, Rebecca provided you a few good ideas for getting involved in your community. I would also add a visit to your local library (in-person or online), as they often times have plenty of community information available.
For information on college, I would first talk to your school counselor or the college advisor at your school. "Good" could mean a lot of different things, so try to think about what it is you're looking for in a college/university. If there are schools that you're already interested in, visit their websites to learn more about what kind of students succeed there, and feel free to contact their admissions offices to gain a sense of their admissions criteria.
