Comma in English

I've been learning English for 8 years and I think I speak English relatively well. However, commas in English keep bothering me. No matter how I put them in the text, they always seem to be misplaced, according to my teacher, who is on the other hand incapable of telling me the exact rule, when comma shoud be used. Would please somebody tell me the rules of comma usage in English? I'd be very grateful.

In my language, there's a simple rule. We use commas to seperate clauses. Whenever you have have two finite verbs in one sentence, there must be a comma between. Does this rule apply to English as well? I am asking, because I've seen clauses without commas many times...

Thank you in advance.

I guess great minds think alike. Or is it, fools seldom differ? Lol.
