If you just have a good idea for what you want to do it'll be easy to meet that mark! As long as your sacrifice sleep, anyways. :p Whenever you're at the computer have your script open and write like you're posessed, and whenever you're away be htinking and planning and working out your plot. =D You may even finish early!
I have nothing witty to say here. Please move along.
You can definitely finish! 20 pages a day is DEFINITELY possible! Put in some work and you'll get it done :)
Think about your script when you can't be working on it and work on it whenever you can. If you're a fast typist that makes it even easier :) And don't worry about it being good, I pretty much have been doing stream-of-consciousness script writing (where you write whatever comes into your head) and it's really easy.
I have 8 pages with 3 days left to go. I moved across town, and that took most of the month. My computer is now unpacked, and I'm about to set it up. (I'm writing this at the library.) If I can write 30,000 pages in a week, I can write 92 pages in 3 days. Now for the most compressed Panic Time in my WriMo career -- at least since I wrote 40,000 pages in 3 days for FebNo '08...
I stopped the moment I got home and collapsed in exhaustion. The move took too much out of me. No Panic Time this month. I was pretty much finished the moment I packed up my computer and started the arduous task of moving. At least I won't have to deal with that next year...
