Which AP exams should I take in my senior year to best prepare me for an L&S CS major?

So I’m deciding which AP tests I should take this year (skipping required courses is always a good thing, but is taking ap exams for the sake of registration priority really worth it?)
The four I’m choosing from are AP Calculus BC, AP Microeconomics, and AP Macroeconomics.
The tests cost about $100 each and quit a bit of preparation, so I don’t want to take an exam for it to have no value.
Thank you!

UCLA does not have L&S CS
the closest it has is L&S Linguistics and Computer Science, but just plain CS is only in Engineering

As a CS student here, I second what Masterball says
Anyway, the tests that give you credit are Calculus BC (it lets you get out of taking math 31a and 31b, so this test is definitely worth taking), Chemistry (lets you get out of chem 20a), English lang/English lit (lets you get out of intro english requirement) and Physics C: Mechanics (lets you get out of physics 1a). AP micro and AP macro let you get out of econ 1 and econ 2, but as a CS major, you most likely won’t be taking those classes anyway so taking those AP tests isn’t that important.
All the other tests increase the number of units you have but don’t let you skip out of classes; if you come in with over 60 units there’s a good chance you’ll have junior standing by 3rd quarter and will thus have an easier time signing up for classes.

tl;dr: take BC, econ tests aren’t as important
