Cloud Bunny:
The answer to your questions are on this thread, but in summary for me:
3 questions the same - very similar answers. 15minutes editing.
One totally different question - couple of hours to answer.
I edited my answers just in case they compare them to a previous application, but I think the premise of 'if they worked last time they will be good enough this time' will see you through. Spell check, grammar check, proof read and DON'T go over 200 words! For first-timers, if you were to spend less than three or four hours answering the questions, think very hard before you submit them. Just my advice.
Hope this helps; good luck - it's worth it.
