How exactly do antirequisites work?

Math 2A03 and 2ZZ3 are antirequisites for each other. 2ZZ3 is the course I need to take but lists 2A03 as an antirequisite. If I take 2A03 will this satisfy the credits i need for 2ZZ3?

Thanks for the help!

I think you HAVE to take 2ZZ3, but once you take 2ZZ3 you are not allowed to take 2A03.
That's usually how antireqs work.

yes, if two courses are antirequisite to eachother, you can not take both. you will only get credit for one of them, because they cover similar material. If you want to take 2ZZ3, do not take 2A03!
