Forgotten to answer question
If you want an A+ then of course you could ask. Maybe he will consider the previous draft, maybe he won't; but it never hurts to ask.

You should be aware, though, that he is not obligated to give you points for it; it is completely your fault for forgetting to answer the questions. Therefore, don't demand points but ask nicely if there is any chance to consider the draft, you will have better chances this way.
