Removing some detail on course pages

I have tried my best to search through existing posts to try to figure this out for myself but I seem to be not on point.

What I would like to do is delete from the course content/overpage:
You enrolled on, Who can enroll, course language and price.

I would also like to delete the link at the bottom which says "this entry was posted in. Bookmark the permalink.

On the course dash board I would like to remove the links that show under the 'details box' which says ' withdraw' and 'course details'.

Hopefully you can help.

Many thanks!!
