Letter of intent will NOT hurt your chances, therefore I recommend you write one, especially since this school is your #1 choice.
What to write?
State that umdnj is your number one choice, elaborate why. You may include why its better by comparing it to all the other DO schools you applied. For example, of all institutions umdnj is my number one choice because the academics are the finest amongst all osteopathic schools. By integrating the curriculum with intensive patient exposures, I feel will best prepare me for clincal rotations than any other DO school. Hence, I need not say more, now where do I sign my acceptance letter. (Dont Use this last sentence).
Keep the letter short, about one page, size 12 font, single spaced or double spaced, either one is fine.
If you have done something worth mentioning since your application mention it. If you have to ask yourself 'should I say I did so so' then most likely its not worth saying it.
Good luck.[/quot👍
