<p>worth it to buy the solutions manual? and how hard are the tests?</p>
<p>Solutions manual…definitely didn’t use it at all last year, and still aced the class. That is in part, however, due to me having a fantastic physics teacher in high school. The tests in 41 were by far the most reasonable of the 40-series in terms of difficulty, length, etc. They’re also curved pretty generously, or at least, they were last year.</p>
<p>is the transmitter needed??? lol we havent used it yet</p>
<p>Nah. Never got one, never had any problem.</p>
