Don’t panic! I hope it isn’t already tomorrow. Start by writing down a list of what you’re pretty sure you know about the topic. Then write down questions you still have. Then craft a thesis that unifies most of those lists. Then re-arrange the lists into an outline: group ideas by how they’re related to the thesis you’ve created. Treat each group as a paragraph (some may be multiple paragraphs if more complex.) As you encounter questions, answer them as well as you can, but don’t get stuck on them. The key is to keep writing. Don’t get caught up in things that slow you down. Go! I believe in you!
