Writing essays can be challenging; you have a due-date, pressure to do well for a good grade, and the pressure to make a good impression.

First things first: be confident. Confidence is definitely one of the most important things to remember when writing a good essay, because, just like when you're preforming, you nervousness comes out in your work, no matter how hard you try to hide it.  

It helps if you are sure you know what you're talking about. Study up on your subject, memorize fun facts, go the extra mile. When you feel good about your work, others will too.

Using proper grammar and "big words" help to give the reader a feel of your knowledge, so to speak.

I find that when I use larger words, people respect me more.

Example:

There is a prodigious amount of things to say that can make you sound eloquent. Using anomalies and such is a good example of this. When you speak eloquently, you make the things you say less ignominious, even if what you said is utterly taboo.

Basically, I just said:

There is a large amount of things to say that make you sound like you can speak really well. Using unusual occurances and things is a good example of this. When you speak beautifully, you make the things you say less shameful, even if what you said is simply not okay to say in public.

Please note: Eloquent means fluent or persuasive in writing, but can be used differently in certain circumstances (such as in the example paragraph).

Do you see how my first paragraph seemed better than the latter? In truth, I was a little nervous about writing this chapter, yet I covered it best I could with my extemsive vocabulary and knowledge of how to use grammar properly.
