<p>What is it, and do all students need one?</p>
<p>Not all classes need them. Just wait and see what your professors policies are. Clickers are little devices where you can answer questions remotely, typically used in large classes.</p>
<p>Thanks for the info and advice!</p>
<p>My D was told all FRESHMAN must have the new clicker. $50!! She got hers included with Tech Prep, so we saved a little bit of money!</p>
