Pro tip: if you have a hard time to reach the word limit, just write redundant sentences that add nothing to the essay. Just reiterate what has already been said before, but with different words and sentence structure. Then you will never have a hard time reaching the word limit. It’s not hard. Don’t worry if the sentence is redundant. If you keep your word choice varied, you’ll disguise the fact that you actually have nothing new to say. Word limits will then be the least of your concerns.
