You have achieved a lot and should be proud! But schools “like Yale” are extreme reaches even for valedictorians with perfect test scores. I commend you for recognizing you may not have the guidance needed to navigate college admissions.
The most important thing is to identify your safety/highly likely school… one you would be happy to attend, have a very good chance of admittance and can afford. Since you are in CA this may be a CSU or CC>UC with TAG. @Gumbymom @ucbalumnus Do you have suggestions for safety schools for this student with a $20k budget?
I will hold off on the rest of my post as I just noticed @BuckeyeMWDSG asked my next question. We can best help you once we know if need-based financial aid will get you to your budget or if you will need merit. Let us know!
