Chance me for UCs and some other OOS schools [CA resident, 4.0 UW, 35 ACT, Undeclared/Biology]

Made me smile. Thank you. This will make you a memorable applicant. (But is your high school class really composed of 567 male students ?)

Northwestern & U Chicago will be tough in the RD round. Will need specific reasons for NU. Of course, Yale, Dartmouth, & Notre Dame will be tough.

Based on your strong interest in tennis and on your intended major area of study, Emory University in Atlanta, Georgia would have been an interesting choice which awards significant merit scholarships.
