<p>In the upcoming summer I am taking part in a prestigious internship (ranked in top 10 by Princeton Review) which will last about 6 weeks, until a point in time when there are only 2 weeks left before school reopens and I return for senior year. For the last 2 weeks should I shadow a CEO in India, or work on my IB stuff (Extended Essay etc.)? Which will be more useful in the long run, e.g. when I apply, must consider that the predicted grades that are sent do not account the actual grade I get for Extended Essay?</p>
