Trading in old Mac

I have a Mid 2011 13” MacBook Air that runs pretty well after being completely restored (it used to be my mom’s, but she was complaining of it running slow as she had so many huge apps on it). My problem, however, is that I need a newer computer for school.

The only problems that it has is that it’s really finnicky when the wifi isn’t the strongest, and that the battery doesn’t last long enough to get me through a school day without being plugged in at all times. Otherwise, it works like a charm, and is reliable when it needs to be.

All I need to know is if I can go to an Apple Store or somewhere else to trade it in for a newer computer.
