I just did a quick google search and quite a few people say this:

If you have a comma or period, you have to put it inside the quotation marks. However, when it comes to exclamation points or question marks, you can change where you place them depending on the context.

For example: If your sentence is a question, then the question mark goes outside of the quotation marks. If the quote you use is a question, then the question mark goes inside the quotation marks.
