If you are getting B's at high school is it possible to get full scholarships for collages?

Not for their grades, and even those with straight A seldom get full scholarships. Most people will have to get government grants, student loans, and work part time to pay for college

It's possible only if you have a talent that the college really wants to nurture -- are you a fantastic player in a particular sport or do you have a unique ability of some sort? Writing a heartstrings-pulling letter to Oprah and getting on her show might get you a full scholarship from her. (It's been done, so I know it's possible.) If you have done a newsworthy service project in your community, say, caused a no-kill animal shelter to be built or set aside farm land and found workers for a game reserve for aging zoo animals, a vet college may give you a full ride. If you are a true horse whisperer or have a knack for understanding what dogs are thinking, a college that has a animal behaviorist program might look twice at you.

Have you checked with various colleges in your state, for instance, to find out what they want back from a student if he gets a full ride?

Hi, jdouglas!

Do you play a band or orchestra instrument?

Thanks!

There are lots of smaller scholarships, VFW and American Legion gives them to members children or children of people with prior service. Many places where parents work may offer something.
There are 1000's of various scholarships, what has to be done is to apply,

... and DO NOT ever pay to get a list of scholarships or scholarship information! All of the information is free! There are books at your local public library that give details on the scholarship, how to apply, etc. There are web sites too that give free information.
