Dear Ms. Amador,
I saw the posting on www.monster.com for a Graduate Assistant for your college math department. I would love an opportunity to apply for this position, and have included my resume accordingly.
At present, I am attending Paul Quinn College for a degree in Math Teaching. I have had the pleasure to take a number of the classes in the department, and feel well versed in the concepts and curriculum supplied. I know that this opportunity would greatly enhance my learning for a successful career in teaching. I am aware that this position is one that is greatly coveted by likeminded students in this field of study, but with my experience, great communication skills, and background in my studies; I know I make for the best choice.
Please give me a chance to interview for this great position, by calling me at (555)-555-5555 to arrange for a desirable time. Thanks so much for your time.
