I will only comment on UCLA. Very diverse but competitive school. If you are not a California resident or have an unlimited budget, UCLA might not be a good option. If you are OOS, they offer little to no financial aid and you should expect to pay around $65K/year to attend. By the time you apply, it could be even more.
To be a competitive applicant, target around an UW GPA of 3.95 and SAT score of 1400 and ACT of 32. Also EC’s and essays are very important so you want to focus on Leadership and community service.
