Quiz 3 results were not so greatshockingly only a little over 0% at first pass. I think it was a combination of thingsdifficult material, a level of execution in problem solving is just so much higher than anything you have seen, and of course, the fact that it is already Spring Break in many of your minds. , ZLOO GHFLGH DIWHU WKH EUHDN RQ DQ\ NLOOHG TXHVWLRQV Here is hoping that on the other side of spring break that VWXG\LQJ IRU H[DP 2 begins in earnest. 3.
