Now that is funny considering all the crappy stuff publik skoolz do and spend money on.
Seriously ?
Here is the deal with this. If these kids actually did their homework they would pass it just fine. Now by homework I don’t mean just the assigned problems at the end of the chapter. You do ALL OF THEM.
Most math textbooks have the answers in the back to either the odd or even problems. The instructor book has the answers to all the even numbered problems worked out. So when quiz/test time comes...where does the instructor go to get the problems for that exam? Could it be the instuctor’s book? The exam is the even problems or some set of problems similar?
This was my experience in every mathematics class I took in high school through partial differential equations and numerical analysis in college.
You don’t do the assigned....you do them all, and you will get an easy “A” because you have seen the problem before. Problem #7 on the exam was # 22 on page whatever from the relevant chapter.
