Your list of clubs and activities are similar to many other students in your demographic who are also applying to the T20 schools . You need to cull your list of activities - you can only fit 10 in the Common App . And rank them in order of significance. You will have limited space to describe them, so you need to think about how to best to summarize. If you were able to bring a new dimension to some of your activities, add that in the description. For example, did you bring in a new perspective to the Tamil curriculum that you’re helping out in?
