Moodle grades

Hello guys, I'm not sure if I'm doing this in the right place. But, here we go...

I use several content types with moodle. And it would be nice, if all the content types could have an option to save the highest grade. Because, sometimes, the student just want to access the content for a review.

Wonder that, I have a Interactive Video content. And the student just want to watch the begining of the vídeo, just to solve a doubt. In this case, we don't want to force him/her to watch the whole vídeo, right?

So, it's something to think about.

Thanks!
