Which is the best strategy to follow when you write a report or an essay

Know what you're writing about (aka topic), give yourself a little time to brainstorm what you should write. If there isn't a extreme time limit (like 50 min to finish it), then allow yourself to write a couple of rough drafts to have a basic idea of where you'll be placing your ideas. Then, write out your final draft neatly and preferably in pen (when you get to high school and college or have a certain job you have to do that..) lastly. double check and edit your report/essay- make sure it free of grammatical mistakes, etc.

On the other hand, if you don't got a lot of time, skip the rough draft and go to final draft, but he extremely careful (don't overthink it too long though since you have a time limit)

Voila, there's the best strategy on how to write an essay.
