I am confused about how the EC/activities sections of the common app works. If there are only 10 spots, how can I fit 13 activities if 5 are clubs? Also, let’s say I am the president of 3 of those clubs, can I put President for ClubA, ClubB, and ClubC just for one slot of the 10 in the application?
There is also an Additional Information section you could use for some further explanation or possible to add a couple of other things you have done – 650 word limit. But be judicious - don’t list everything under the sun and dilute what’s most important.
My kids both went over 10, and had very good results. Here are the rules they followed:
Anything not done past 10th grade was dropped unless there was a significant award or relationship to their planned major.
They grouped stuff. Like they might have an activity called “Music”, then said “See Additional Info section.” in the description. Then a header in Additional Info that said Music, and concisely bulleted out the activities and awards in the categories.
And they still went over 10 (small HS to kids were encouraged to do a lot of activities, and busy summers). So then they had a header in Additional Info they called “Additional Acticities”, and they bulleted those out.
Be sure you order the Activities so the most important ones to you are first, though.
D and S were both able to combine activities into that space as @intparent suggests. “Music” was one they both used to include multiple activities, D did two summer academic programs that were similar except for the class taken, those went together, etc.
