I had my phase 3 on a Tuesday and they phoned me on the previous Friday to say that they hadn't received my answers yet (even though it said that they were just due on the Tuesday). I'd therefore try and get them in no later than about a week beforehand. But there certainly is not any rush to get them in first or anything like that. I wrote my answers and then got a couple of people to comment on them and to make suggestions as to how they could be improved in fact so when I finally submitted them I was pretty happy with what I'd written down and was glad I'd taken the time to do so.
