if you have any siblings that will ever be in college at the same time as you, your eligibility for aid will increase with more kids also being in college. Plug the numbers into the NPC if it’s a factor so you can see the effect on your aid.
also, along those lines,:some schools don’t allow you to apply for aid in subsequent years if you didn’t apply as a freshman (keeps people from trying to increase their chances of admission without FA if they really need it)… so if you have siblings that would go to school in later years, plan accordingly.
