Now you are looking at the remaining 20% of your word limit being your conclusion. Percentages may vary if larger word limits are being offered. Ensure you state why you are interested in this field of study; state the key points from the body of your essay (e.g. accomplishments, experience and interest). Ensure that you keep it brief, to the point and leave out the clichés. Just as you started your personal statement with an attention grabber, make sure you finish your personal statement with one or two sentences that are positive and leave the reader remembering your statement while they are reading the next few.
When you allow a fresh set of eyes on your admission essay it is almost as if your personal statement is getting practice. After all, your statement will ultimately end up being read by one or more people while your application is being reviewed so it makes sense that a well read personal statement should do better in its final stages. Why have the reviewers catch the mistakes that someone else can catch beforehand? It is far better to catch a small mistake that can cost you admission, before it actually has the chance to cost you.
