When I was studying for my CELPIP exam I got material from them. Unfortunately, I can not put the PDF to the public because it has a watermark with my personal email. But I can put you here what it says.
CELPIP's seventeenth error as they state:
The comma is the most frequently used punctuation symbol in English. As a result, it is often responsible for the most errors. Since there is a dozen of instances where commas can be used, the rules for comma use are extensive. The most common are presented here. We suggest that you review Unit 2: Run-On Sentences since it also covers comma use.
How to Use the Comma
You will use the comma in the following cases:
- To separate independent clauses joined by coordinating conjunctions such as or, and, but, and for in compound sentences.
Miguel will be busy at that time, but you can call me instead.
- To separate words, phrases, and clauses in a series of three or more. The comma before and in a series is optional.
You said: one, two and three.
- To separate introductory words or phrases from the main clause.
Since 1949, I have not been that surprised as I am today.
- To separate extra information that the reader does not need to understand the main clause.
Miguel, who is a successful business dog, likes to take a walk every day.
- After a salutation in a friendly letter.
Commas should not be used to separate compound predicates.
- Mike barked goodbye to us, and went to sleep.
- Mike barked goodbye to us and went to sleep.
