How should I ask for a college interview via email (HELP!!!)?

I'm applying to MIT, and the first test in the application process is that you have to email the interviewer yourself to schedule an interview- there is no form. How in the h*ll do I phrase it so I don't come off a brown noser, but also not disrespectful?

I hate the first sentence!!!! I'm not supposed to start with 'I", but what do I say?

This is what I've got:

Dr.X,

Thank you for conducting these interviews, as it truly does provide a valuable perspective. I am a student at Y High School in XYX. I am applying to MIT early action, and I would like to schedule an interview with you. I have a somewhat unusual school schedule, so I have free time in the middle of the day and after school. Please let me know what would work for you.

Thank you,

First (Nickname) Last

I actually want to get in to MIT very badly, so how can I ask without sounding stupid???

Thanks for reading!
