I'm a little confused here. You first say:

"An interesting thing that I learned about today, is that the current 2nd semester class got caught cheating"

But you later go on to say:

"I guess they couldnt [sic] catch the few students who were cheating"

Perhaps what you meant to say is that some among the second semester class were suspected of cheating. As a matter of fact there was insufficient evidence to prove that anyone cheated.

I would hope that the administration would not be so immature as to punish an entire class for the alleged sins of a few. So far, that doesn't seem to be the case....thank goodness. The block 4 histology test was extremely hard and the majority of the class failed, but the block 5 test yielded the highest class average of the semester.The level of difficulty in anatomy remained unchanged and in fact many did extremely well on the final exams.

Have the profs decided to make semester 2 much harder? I guess we'll find out soon enough
