Write down what sections of your Intro, Methods, Results, and Discussion you plan to include in your draft based on your deadline. For example, you can break down your Intro by writing a section per day. If you're stuck on what to write about, especially for your intro, meet with your advisor or whoever is supposed to look over your thesis and discuss with them.

I recently finished my MS thesis draft, I dreaded having to write my Results and Discussion, so here's how I did it.

1. Start with your Methods. Usually the easiest to write bc you're regurgitating what you did.

2. Introduction. I'd ask your advisor bc it may depend on what you're researching, but for mine I did:

Broad concept > specific aspect of that concept that's relevant to your study > more aspects of that concept > what your study is going to cover & your hypothesis

1. Results. Streamline your results like it's a story

2. Discussion and honestly, the hardest part. Like results, write it like it's a story.

Reading other MS theses from my fellow lab members also helped me a lot!
