Outside scholarships does not always affect financial aid as I have seen mentioned.

I am going to round some numbers here for simplicity.

Original award:
Grant: $18K
Separate scholarship from school: $5K
Subsidized loan: $5.5K
Unsubsidized loan: $2K
Total: $30,500

After they applied the outside scholarship:
Grant: $16K
Separate scholarship from school: $5K
Outside scholarship: $8K
Subsidized loan: $2.5K
Unsubsidized loan: $5K
Total: $36,500
