summer programs??

I got admitted into the Stanford humanities institute summer program for sociology, and the tuition is about 7,000. But I’m much more interested in science, and I got into the Columbia summer program for Explorations in Genetics and Molecular Biology (which has a tuition of about 11,000 total). I’m interested in both subjects (science more though) but the price makes it really hard to decide. i didnt get any financial aid either :frowning: what should i do?? i need to decide by March 12!
