This is the general page for all UCs in terms of AP credits.

Since Berkeley is on semester, you would divide the numbers by 1.5. For the most part, you get credits for anything 3 and over. In general though, all the credits does is to pad your credit numbers for the purpose of graduation. In many cases, the credits will not do anything for you and from what I’ve heard, at some point you may need to withdraw the credits so that you don’t go over limits later on. None of the AP credits will help you with breadth requirements.
For L&S specifically, here are the college-specific rules for the courses that will in many cases help you by skipping classes:
Computer Science
Computer Science Principles: Score of 3, 4, or 5 satisfies CS10 and the Quantitative Reasoning requirement.
English
Literature and Composition: Score of 4 satisfies Part A of the Reading and Composition requirement; score of 5 satisfies the entire Reading and Composition requirement (Part A and Part B).
Language and Composition: Score of 4 or 5 satisfies Part A of the Reading and Composition requirement.
World Languages and Culture
Chinese Language and Culture, French Language and Culture, German Language and Culture, Italian Language and Culture, Japanese Language and Culture, Latin, Spanish Language and Culture or Spanish Literature and Culture: Score of 3, 4 or 5 satisfies the Foreign Language requirement.
Mathematics
Calculus AB: Score of 3, 4 or 5 satisfies the Quantitative Reasoning requirement.
Calculus BC: Score of 3, 4 or 5 satisfies the Quantitative Reasoning requirement.
Then you also have major-specific rules. For major-specific classes, AP credits will help you skip a class. For example, getting a 4 or 5 in both AP Macroeconomics and AP Microeconomics allows you to skip Econ 1. For CS, if you get a 5 on Calc BC, you can skip out of both Math 1A and Math 1B.
