I have been keep researching on UC Transfer, and formulated another question;
Unlike UCB’s EECS with 3.88-4.00 admit range, UCSD’s CS has lower, 3.68-3.92 admit range for 25-75%. And the admission rate is 26%
Does this mean, if a student has 3.93+ GPA and completed all required and recommended courses, she will have very high, 50% or even 75%+ chance in general?
I would say yes.
If a student has a 3.92, then she has a higher GPA than 75% of applicants. Completing all required and recommended courses definitely improves her chances. Note that being at the 75th GPA percentile doesn’t translate to having a 75% chance - but if a student has a 3.93+ GPA and has completed all required/recommended courses, she will have a very strong chance of being admitted.
If she has a high GPA, though, she might want to consider applying to Cal’s CS major instead of EECS. Being situated in the Bay Area is, naturally, a fantastic advantage for being employed in the tech industry (assuming that’s what she wants to go into).
Thanks. Cal would be a dream school, which is said to be reach for everybody. 
Unfortunately there is not enough info in the stats the UCs release to know. 75th percentile just says that 3/4 of admits had that gpa or less; its still possible at a school like Cal that they only took 50% or less of the kids with that gpa. What is really needed is a chart like the med schools give at https://www.aamc.org/data/facts/applicantmatriculant/157998/factstablea24.html
