How to update multiple pages from one page?

I have to update some common fields in many pages so is there any way out to update it from one page rather than opening and editing so many pages in drupal.

Let me explain it: Suppose I have 100 pages of various courses which our institute offers and all the pages have few fields in common such as duration and fee of the courses. We use to update fee randomly and when we want to update in all the courses then always we need to open each and every page one by one and it really sucks.

Is there a way out where I can have all the courses with their duration and fee fields only all on the one page and can change easily from one page to update others.

Hope I put my point clearly.

thanks
