First of all be careful because some people will try to take advantage of students looking for help. The professional standard is not to charge to apply for financial aid or a scholarship application or search. Any legit help or application is free.
Have you already submitted your FAFSA
? Students started applying for next school year Jan 1st with the 2016-2017 FAFSA. It is to your advantage to submit your application with estimated tax info as early as possible.
Check with every school you are considering to find out what they recommend. A lot of schools will have their own foundation scholarship application.
Check with your state
to find out if they have a state scholarship application like we do here in Oregon
Use the Dept. of Labor free scholarship search tool
Apply as early as possible and remember to check back on each application and stay in contact because there are usually follow up steps for every application process.
