I worked in WP's help desk for a long time awhile back; you should go there or the Teahouse to ask this question.

However, the answer is that you need to move it to an appropriate name in the "(Main)" namespace; right now, it is a subpage of your userpage in the "User" namespace. Your sandbox is to make drafts. You may find it easier to make future drafts using Articles for Creation or the draft namespace. You can also create a page directly in the main namespace without starting in your userspace, but you may want to be prepared to build it up very quickly or it may be considered for speedy deletion if it's not very complete (as in, if it's a one liner with no indication of importance and no template saying it's a very new/under construction article).

EDIT: Actually, don't do that; I found your page over there and you should have just made the edits directly to the article you wanted to change, Rajshahi College, instead of creating a fork of it in your userspace. There is no way to move your version on top of that version, especially considering it is not a complete rewrite.
