For the story chapters, you need to beat it in a short time as well.

I think that there are some guides to the story missions in the Gameplay & Guides section. You'll just have to search for which mission you're looking for.

I don't have the time at the moment to find them all but might later on if you still need help. The story missions can be tricky at times and doing them on a C run helps me out first. Doing a C gives me an idea of what I need to do and then I can do a higher rank but only quicker.

Hope that helps!
