AP Credit for UC Berkeley

So I’m attending Cal and I am in the college of engineering. These are my current AP Scores:

World history (3)
English language (5)
Biology (4)
Calculus AB (5)
Psychology (5)
Physics 1 (5)

I just got off the phone with a staff member from the college of engineering, and she told me that the max units that a freshman can use from AP tests is 20. I am signed up for the following AP tests:

Calculus BC
Physics 2
English literature
Macroeconomics
Government (US)

Which of these tests should I take if any?

5 on calculus AB = Math 1A (but try the old Math 1A final exams to check your knowledge)
5 on English language = reading and composition A (e.g. English R1A)
4 on biology = Biology 1A/1AL and 1B
5 on psychology = lower division humanities and social studies breadth (maximum of 2 from AP credit allowed, including the reading and composition); may take more advanced psychology courses since the psychology department accepts a 4 in AP psychology in place of Psychology 1

4 or 5 on calculus BC = Math 1A and 1B (but try the old Math 1B final exams to check your knowledge; CoE recommends that students with a 4 take Math 1B)
English literature = (for CoE) same as English language which you already got the maximum possible
physics 1 or 2 = nothing (these are non-calculus-based, and CoE requires calculus-based physics)
3 on world history, macroeconomics, US government = nothing since you already have 2 lower division humanities and social studies breadth from AP credit

Note: if you later switch to a division other than CoE (e.g. L&S, CoC, etc.), the AP credit may be different, causing some of the AP credit to be worth more and some to be worth less in terms of subject credit.
