Counting words

On the Master in Research (MRes) I used to take around three weeks to write each assignment. If I assume I can now write 5000 words in four weeks, and I need to write a PhD dissertation of around 80,000 words, then I need over a year to write it. If I make it longer, and the maximum length is 100,000 then I need another four months.

Conclusion:

• write quicker
  
• use everything I've already written
  

or I'll be struggling to get it in by my registration cut-off date of 31st September 2011.
