Submitting Your UCAS Application _ UCAS forms can be submitted either in paper form or electronically. Either way your personal statement needs to be typed up electronically and must not exceed 47 lines (~550 words).
Just as a strong personal statement can get you in, a poor personal statement/essay can quickly eliminate you from the mix. When a medical school committee has a few hundred applicants, seeing typos, spelling mistakes or bad content will quickly move you to the bottom of the pile. The personal statement is a quick way to "weed out" similar applicants. With two similar applications, the personal statement can decide who gets an interview and who does not.
