Columbia Science Honors Program questions and doubts (Not really a competition)

<p>Hi I'm applying this year for the first time to the SHP program and I have a bunch of questions.</p>

<p>On Feb 27, the completed app is due. Is that just the personal info, high school info, grades, and essay?
and by March 20, my school has to mail my transcript and my recommendations have to be submitted? </p>

<p>Also for recommendations, I'm getting 3 recommendations, one from my math teacher, one from bio and one from my C++ teacher. Am I allowed to get on from my C++ teacher and if yes, should I put him as a math or science instructor?
Also I have a bio tutor who is the AP bio teacher at my high school. I don't have him as an instructor at school, but could he send me a recommendation? Would my health teacher work as a recommender too because we learned about anatomy and the human body in health. Also, how many recommendations is the max or how much should I have at most?</p>

<p>Lastly, how do I pay the 30 dollar fee for the application?</p>
