Where do I put coding on the app?

In my free time, I’ve taken some courses online that helped me learn HTML, CSS, Javascript, and Python (coding languages). I’ve spent usually a half hour 3 times a week learning the languages, and I’d say I’m proficient at them. Is this worth putting on my common app, and if it is, how should I do this?

In addition, I might take a Coursera class or two over the summer if my AP work isn’t too bad. Can I put that on the app?

Thanks for all the help, and in case you ask, I just enjoy learning if nobody’s around and get bored of games.

I personally put all my miscellaneous skills in the additional information section at the end. If you can quantify the hours you put into it, you could probably even make it an activity.

I would put it in the activities section.

Thanks for the help, I figure that it’s a big enough thing to put on the app and actually would be useful as a student. I’m hoping to finish learning C++ by the time that apps go out so I can be more qualified sounding for engineering schools.
