Letter Of Intent For Graduate Schools Letter Of Intent Help?

Letter of Intent help? - letter of intent for graduate schools

I shall write a letter of intent for graduate programs. I wonder about a few things ... Is this really a good idea, e-mail and ask the teacher what they want in the letter (because) no instructions? There is also a good idea, the names of people I know mention donated to the program (it is a small program) is one of 16 students per year, and I was inspired by the work they have done for them? Thank you!
