If you can find 2-3 years that’s not enough. Forget outside scholarships, they are unlikely. Perhaps you can find some local ones but they are typically small. The national ones are just crazy hard to get.
You said under $50k so it’s there. You may be able to talk to a counselor to ensure you filled out the NPC properly. You’ll find different schools have different calcs etc.
But this is a solid start.
I was saying u of Arizona. Not ASU. Better for your situation. Also has Honors. See link. I put a few more too
U of A is $30k off of 38k
