It depends on what you want to do. If you are going into a very competitive field or want to work in a prestigious company in a big city, the school you went to makes a difference. If you want to do a service type job or work in a smaller company in a smaller town it is not as important.

When I applied for colleges, they looked at grades and placement test scores. We were well educated in high school and could pass the tests. They did not have to look at volunteer work, etc. Now, I guess they do look at that stuff. There should be a number of places you can go. Try an animal rescue league. They always need people to walk dogs or cuddle kitties. Is there a VA or other hospital in your area. You can push wheelchairs, sit at a reception desk, read to older people. Sometimes, if it is a nursing home type of facitly all you need to do is be willing to visit with someone for awhile. If you have the temperment, hospice groups can usually use volunteers for office work as well as transporting people to appointment, etc.

My main point is you do not need to stress yourself so much. It sounds like you are smart enough that your grades are good. You are ambitious enough that you are not sitting at home playing video games in your free time. You can plan your time and set your priorities. You'll do fine. Once you finish school you will find out that life is about so much more than your education and job. Start enjoying yourself a little now.
