Is TA-ing a good idea?

Hey guys!
So I have 3 APs and am on track! I was thinking about being a TA for my government teacher so that I can gain some experience as a TA. My major is Econ/Stats/Public Policy. This is my second semester of high school senior year and so I can’t take any core classes such as science but I can take an elective. So my question is: which is better? An elective or TA? Will it look good on my app? Or will it look like I am slacking off (due to the stigma that surrounds TAs being lazy)

IDK about the stigma of being lazy --I am a TA for College Bound Physics and I have to correct all the homework(without an answer key)!

It definitely looks good on your app, especially if you can get a teacher recommendation from that class.

Second semester of senior year?

You previously said you have 8 AP, plus college courses.

If this is advance planning for spring of senior year, and by then you’ve completed a rigorous schedule. it’s fine. If this is for sooner than that, and you really are thinking tippy tops, TA in high school won’t be seen as a special plus when it replaces something academic.
