When I was doing my student teaching, I was giving a test on the Protestant Reformation, day of the test I told everyone, if you dont know an answer just write 'corruption in the church' and I will give you a point as that is the main idea of the chapter. Didn't matter what the question was, true/false, short answer, didn't matter write those 4 words and you'll get a point. I still got entire pages back blank.

There were enough questions on the test, that if they wrote corruption in the church for every answer they could have passed with a C.

That shows the lack of effort students today put into their school work. It's not always the teachers, who suck. Many times, it's the students.
