10. Use poor spelling or poor grammar _ This one should be pretty obvious. Academics on admissions committees are generally high achievers with high standards who won't disregard even simple typos. If your personal statement is not technically perfect, it can make you seem sloppy, lazy, or inattentive, which are not qualities anyone wants in a future colleague. Remember that the people skimming your essay are seeking a reason to reject your application and make the pile of possible admits smaller. Always get someone with strong writing skills to review your essay.
The entire college admission process is grueling and psychologically taxing, but little is worse off than writing the personal statement for college applications. At first, you may think that the personal statement for college is going to be easy; just sit down and write a few words about what inspires you, or what you want to accomplish, etc and that's it. However, personal statements for college are more than that. You see, the fact is that when you are in high school, you probably have not much to do as far as writing is concerned. You could easily breeze through on the five paragraph essay, and write an endless series of meaningless papers, getting straight A's, as well as they are properly organized and formatted.
