Can I finish my thesis by the end of this year?

I am now writing Chapter 4 and 5. They are all about quantitative and qualitative findings about teacher cognition in using computer technology in teaching EFL. I think I will finish these two chapter before the end of March. Then I move to Chapter 6 discussion and Chapter 7 conclusion which I would spend 2 months on them. I think in September I would be able to work on the most boring part, Chapter 2. Then finish them up with chapter 1. And take the first four months in 2010 for revision. I will get it done it promise to myself.
