<p>I asked this on another board and no one knew. I have to buy a response card for a class. Found them used on amazon BUT I need to know if they can be reused? Anyone used these in class or bought them used and had luck?
Thanks.</p>
<p>At my school we have a thing like that except it’s called an iClicker and it can be used for any class after the one that you bought it for here.</p>
