Keep in mind that each person has some strong as well as some weak sides. What are yours? Maybe you’re good with writing but bad with gathering data? Then in would be wise to leave more time for the latter.
Don’t try to do everything at once and complete the work overnight. Break it into the chunks you could do per day and work on those. Take your time.
Ask your friend to read your paper and ask for his or her opinion on it. It’s likely that you don’t notice some weak points or some gaps. Don’t hesitate to improve those. .
It would be great to leave yourself a day just to check all the things and make sure you’ve got everything right and ready. Make sure your sources are all credible and reliable since this type of paper would need more precision.
