Beware of the counterexample trap! Example: a propt could say something like: Success comes from hard work. First it will tell you to explain what that means. (I usually give an example to illustrate my point even though one is not asked for. This helps get the message across and can contribute to unity in the overall essay.) Then the prompt will instruct you to do something like: give an example of when success did not come from hard work. YOU HAVE TO BE EXTREMELY CAREFUL HERE! A lot of people make the mistake of doing somthing like giving an example of an UNSUCCESSFUL PERSON WHO DIDN'T WORK HARD! This is totally different and does not address the prompt, yet it is one of the easier mistakes to make.

do be somewhat careful with the counter example. absolutely make sure it addresses their second question. anything will work as long as you state in the 3rd paragraph (if you're doing the typical T-A-S structure taught by Princeton - thesis, antithesis, and synthesis) the circumstances and situations under which it works for the counter example and antithesis; the same applies for the prompt in the last paragraph as well.
budget your time wisely. make sure all questions are addressed. about 10 minutes for each paragraph.
no need to write like a grad student.
make it simple. concise. easy to read. use very obvious transitions and conclusions (i.e. on the other hand, therefore, hence, in conclusion)
moderate any extreme language in the prompt by stating, "in some instances", etc.
i find that a lot of people focus too much on how to write rather than what it is they're writing. i'm by no means a writing expert. i hate writing. but at least my writing is straight-forward enough that a middle schooler can understand it and my examples are very clear. just address the prompt and answer the questions and you're good to go
examples are somewhat important depending on the prompt. easiest way to come up with examples: watch the news and keep a running tab of certain events you think applies to certain topics.
try to have examples for technology, politics and government, advertising, etc.

pick a question or two for each topic and come up with an example or two along with a counter example. you'll find that you'll be able to use the same examples for questions of the same topic.
so that's what i did. didn't do much but think of examples and ended up with an R.
as long as your structure is very clear and your ideas flow from one to the next, you'll be good to go. at least shoot for the 3 paragraph structure with a example supporting the prompt, counter example supporting the opposite of the prompt, and a synthesis paragraph that showcases the different circumstances under which works for which.
good luck.
