I think it's the first draft anyway, so I suggest handing it in early, because even if you don't hand in the first draft until 15, the tutor will give you suggestions for revision, and then let you revise it and complete the final draft. You'd better hand it in early to buy more time for the final draft. Personally, I think it is the final draft. At that time, you have got the opinion of your tutor and have the direction of revision. If you don't want to be constantly asked for revision, you should hand it in a few times before finalizing it, that is, later. Personal point of view.
