Common Application Additional Information

I did a research project over the summer and was intending to publish it in a local magazine but my club sponsor suddenly retired due to personal health issues. I included my research project in the activities section but should I talk a bit more in depth about it and how I wasn’t able to get it published (yet) due to uncontrollable factors in the additional information section? I wasn’t able to say much about what I did in the limited activities space.

Also, can I mention a few interesting things I do in clubs at school? I would simply bullet-point/list a few items that I do. (Again because I couldn’t fit it in my activities section)

I would not include your research paper. That is not what that section is for. You can list it as an activity, and put a few concise bullets about it in additional info.

Same with your other items, although again – be concise.
