The personal statement should contain an explanation of your interest in Bioengineering. You may also use the personal statement to relate important or unusual experiences, such as research, volunteer work, or leadership or cultural experiences. The personal statement is also a place to explain how you could contribute to diversity within the Department of Bioengineering. Factors that contribute to diversity include, but are not limited to: cultural awareness, activities, or accomplishments; educational background and goals; living experiences, such as growing up in a disadvantaged or unusual environment; and special talents.
Finally, you may use a portion of the personal statement to address any academic difficulties, such as a poor performance one quarter or a low grade in a pre-requisite course. If your cumulative GPA falls below the 2.5 needed to apply to Bioengineering, or you have academic problems to explain that are larger than a single course or quarter, please address this through a formal letter of petition (see note) rather than through the personal statement.

Mechanics (spelling, grammar). Don't be sloppy. Use a spell checker, but also reread it to catch errors that the spell checker missed (e.g., "affect" vs. "effect"; "its" vs. "it's"). You don't want your writing to suggest to the committee that you're too lazy or don't care enough to fix typos, or worse, that you're in college and still don't know how to spell.
Formatting. You want the reader to be as comfortable as possible when reading your personal statement.
Type your statement. Make it fit neatly within the allotted space (usually 1-2 pages). Standard margins are 1" all around. Standard font size is 12 points. Laser or inkjet printing is best; avoid dot-matrix printing.
