Have you reviewed my homework? May I check it in WriteCheck now? Is there anything else you would like to add? Is everything OK with it? This is because my teacher keeps correcting the homework and makes some other improvement. But I have not yet received his comments on my work. I want to make sure that my homework is OK so that I check it in WriteCheck.

How do I construct such a polite question? Is this OK: May I ask if I check the same draft I sent you four days ago (with no corrections)?
