Many states award grants or scholarships to students with good grades. A college financial aid office should be able to let a student know if the student qualifies for any state merit aid.
The typical college has many different merit grants. A college financial aid office can offer parents and students information on their options. Note that many merit scholarships are specific to a department, sport or activity. It pays therefore to contact a particular department that a student has an interest in and obtain the pertinent merit aid information.
Also, many private organizations provide scholarships and grants.
This form of aid is typically well below the cost of attendance, often as low as several hundred dollars.
