Scrookie- although I'm not too sure if we can post the questions in the application on the forum (somebody did this the other day and I think a mod removed the post), you can work on them offline.
I would suggest registering on the BA website and 'start' your application. You will then have access to the essay style questions where you can work on your responses offline. You don't have to start your application and finish it in one go... you can save, modify and delete responses and keep going back to your application before you finally submit.
