PROS OR CONS??

Well i had my fluid mechanic mid term this afternoon, silly, its not a test at all..
lets start from 2 weeks ago..
We've complained about our fluid mechanic lecturer through online feedback system around 3 weeks ago and get the response from civil HOD very well, they declared that they already discussed and made a random observation to one of the lecture class. HOD urged our lecturer to have a test to evaluate student's current performance since many students had made the similar complaint.

SO we prepared for the test.. study by our own, totally by our own, main text book and the slides..
As usual, he distribute all the question papers, and people start copying answers from text book since he only cut and paste 1 of the question frm text book exercise. It's an open-book test, fine, we copy from book, its legal..

After 20 min we had our test, he went out from the lecture hall, leave hundreds of students solving the questions inside, without any obervation from lecturer, what he meant by this? Giving us chance to get the answers from others? The purpose of this test if to evaluate the students' performances for HOD, indeed it is calculated into our final marks, its a benefit for all of us as student to score in this test. We don't have other choice, try to get the answer for the questions given. nobody wanna fail in this test of course.

This definitely benefits himself the lecturer as well, because our results gonna be fuking excellent. . so that the HOD wont expell him from this job (perhaps if our results is too bad).
how about Us? we get higher mark in this test but we still have to attend his lecture class for the next incoming 6 weeks. how about our final exam? and how about our fluid mechanics 2 in next year? even if we get a great offer again to copy the answers in final exam and obtain a great result in final, its not over yet. this is fluid mechanic 1, still, 2 is next. our fluid foundation, gg .
