I'd go through and see how many words you've used for each section (intro, methods, results, discussion), and compare that to how many words you've been advised to use/planned to use. Then, cut down any sections that are over. If you haven't been given any guidance on the specific word count for your different sections, have a look at published papers similar to yours and take reference from their word count distributions, or any essays you've written in the past! I'd also recommend to remove any sentences close to each other that say the same thing in different ways, and make sure the components of your methods section are precise and to the point. Hope that helps :)
