Hi there,

I was wondering how coordinating conjunctions work in sentences with commas.

Something like:

I finished my homework, but I should have finished earlier.

I know you can use but, or, and for after a comma. Are there any other coordinating conjunctions?

Also, how does it work with the conjunction so? I many times saw it with a comma before and in other cases without a comma. What would be the right use of it?

Thank you!
