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.
Planning Part B and launching into your first draft _ Planning the structure of your essay and allotting your own word limits to each part give you a framework in which to develop the content. Naturally, there are three main parts introduction, body and conclusion. From the notes you have made previously along with the questions you need to answer, this is where you condense your prompts to fit each of the three sections. Relevance, power to support your application and evidence of who you are is what you are looking for.
