Without looking at what you wrote on Day 2, answer the same questions.
What do you know about your novel?
What do you need to discover about your novel?
Take your time with this. When you are finished, take a look at what you wrote twenty-eight days ago when all of this began.
I hope you know more now. Or that the things you thought you knew have been challenged and deepened.
You are bound to still have much more to discover. We keep discovering until the very end. We discover even after the novel becomes a published book.
