I basically need someone to help me by explaining step by step how to complete the report required.

addressed everything I'm required to, so I need help condensing what I have and deciding whether there are key parts missing that I will need to add. I don't exactly need help writing, but help shortening what I've written and deciding whether or not to write more. I think the first step to getting this done is looking at the writing prompt and my essay and confirming which things I have already addressed sufficiently and which things are missing or incomplete. Level of detail/clarity, flow, and transitions would probably be the second step. "Level of detail" is where I can hopefully shorten some parts while still sufficiently addressing what I need to. But if you think a different approach or order is good, please let me know.
