<p>What is NSHSS? If I were you, I’d pare down my ECs to represent your most important ones and those you spend the most time on and commiting yourself to. On the common app you should be able to put the number of hours per week and weeks per year down so that will help with colleges getting a sense on what you spend your time on. You seem very well qualified, lots of awards, and with somewhat unique ECs. Better than some ND applicants I’ve spoken to recently. Good Luck!!</p>
