Quote From BilboBaggins:
don't leave your conclusions chapter or abstract to the last minute. These are crucial in selling your thesis and your contribution to knowledge. So allow enough time to get them right.
Would agree 100% with Bilbo here; don't underestimate the importance of your conclusion, a good final impression is very important, really spell it out. That's what I did but eh, not until my post viva revisions! Why I didn't just do it first time round I don't know:$
