Dear students, a word of advise in thesis-submission times: you may think you don't need your supervisor's feedback on a first draft of your thesis and skipping it will give you more writing time towards your 'final' thesis submission deadline, but you're almost certainly wrong.
Feedback on a first draft (even an incomplete one) almost always improves a thesis and gets you a higher grade. Professional scientists also ask their colleagues for feedback on their work before they submit it for detailed peer review scrutiny.
In fact, this is precisely why you have supervisors. Use them. And remember, they are also the ones grading your thesis (or one of the people that do) so getting some insight into what they want to see is very valuable.
We see this tendency often. Usually because deadlines approach faster than anticipated, and/or students are reluctant to share incomplete work. This is a shame. First drafts don't need to be perfect, that's why they're first drafts.
If mistakes or omissions are detected in a first draft, your supervisors can explain what's wrong and suggest improvements, if they are first spotted in the final work they will affect your grade. In fact, handling feedback well typically improves your grade too.
Of course there are exceptions, and there are surely cases where a first draft is excellent as-is and feedback will barely improve things. However, the chance that your thesis is such an exception is a lot smaller than the chance that you can benefit from feedback.
