<p>Should I talk about an activity that has to do with my major or an activity about my officer position in a club -- management skills?</p>
<p>Given that you only have 150 words, it has to be compact. It probably doesn’t matter too much, because you can talk about the other in the Additional Information section.</p>
<p>Write about whatever you think is the most meaningful. Which club would you hate to quit? Which club can you talk about what you have learned, how you have grown, etc. If all else fails, write 2 essays and then decide which is better.</p>
