The personal statement is also a great place to explain more serious problems, like less_than_ideal grades or test scores. Don't be afraid to write something like, "I don't test well" in the statement. As long as you can provide a good reason for you app's problems, it's okay to address them directly. You won't be able to hide it from admissions officers anyway, so providing a reason for problems is always preferable to ignoring them.
One caveat in using personal statement help, however, is to make sure that you don't copy these samples and pass them as your own work in your admissions essay. These guides are meant to be just that__guides. Copying someone else's written work and claiming them as your own is one form of plagiarism. Submitting a plagiarized work as a personal statement will surely put your application and your credibility at risk. By making use of sample statements wisely and effectively, there is no reason why you should not come up with a lively, informative, and well_written piece as your admissions essay.
