About:
Currently a sophomore in college working towards my B.S in General Biology.
I've really come to love OpenStudy :) It has taught me a lot of really cool techniques I never knew I could do, and I get the opportunity to share these with other people :D
Subjects that interest me are Biology, Chemistry and Mathematics (particularly Calculus and subtopics in algebra - completing the square)
Turned Emerald 11/28/14. Day after Thanksgiving! Woo!
And turned 99 on 12.20.14 :)
