If you apply to UC Berkeley in the College of Letters and Sciences, they do not admit by major. To declare the CS major, you must complete CS 61A, CS 61B, and CS 70 with a minimum cumulative GPA of 3.30 in those 3 courses in order to apply to the major.
All UC’s are test blind so your ACT will not be considered in the application review.
UCB should be considered a Reach school.
I also have the same question about getting full tuition scholarship for UCB? Does the tuition scholarship amount cover the OOS/International amount of around $44K/year? That still leaves a gap of around $23K/year for Housing, Fees, Books, Transportation etc…
Since you are an International student, you cannot have an EFC which is a Federal aid term not applicable to you. Can your family fill in the gap?
