please help me about where to put a full stop or a comma in this sentence

"ok see you later bye"

thank you so much
A variety of punctuations are available; I think I'd do this:

OK, see you later. Bye.

Students: We have free audio pronunciation exercises.
what about "ok"?

is it just "OK" or "O.K."?
