<p>Do we have to do the problems that are at the end of each chapter in the lab manual? Are they helpful/necessary?</p>
<p>Ah, we didn't have to do those? Were they optional?
I sent like my whole sunday working on those problems. >.<
They better be worth something. :[</p>
<p>are they optional?
what exactly is the pre-lab?</p>
<p>Ah, ok, I just went to lab today so I can answer my own question! :d
But turns out for chapter 4, the problems were optional. The worksheet that we ended up doing in lab were selected from those problems. So if you didn't do it, you'll end up doing some of them for lab. If you did do it already, you're set. I did all of them (better safe than sorry!) so I as finished before everyone and I just left early.</p>
<p>Thanks aerials! :D</p>
