There's no limit on scholarships to apply for. I recommend that you apply to ALL of them you are interested in. Research areas such as your career interest, sports, academic, hobbies, local church, foundations, etc. Check in your local community, your parents employer and with friends and family members. Do not overlook the smaller awards because they can take care of books, supplies, memberships, etc. Start searching for scholarships as early as possible and apply to as many as you can. You'd be surprise at what you could get. Best of luck to you!
Sheila recommends the following next steps:
There is no per se "good amount"... apply to as many scholarships as possible to receive as much funding as you can.
Apply to as many as you can now. Of course most scholarships don't become available until late junior or senior year, but always be on the look out. Also check out RaiseMe and Going Merry. These apps help with finding scholarships as early as your freshmen year in high school!
I would suggest to apply to as many scholarships as you can. Do not put all your eggs in one basket.
