Came across some funny stuff during my spate of tuitioning lately. First up was a chinese model essay a teacher did up for students to study. It was supposed to be a letter to an older cousin expressing concerns over the cousin's recent weight gain.
Quoting the teacher,

"以前你是一个身材魁梧，体格健壮的年轻人，没想到半年不见，你就变得脑满肠肥了。"

Ahahahaha
Full marks for the vocab but where the hell is the TACT??
And it's supposed to be addressed to an older cousin?
If I ever receive such a letter I'll come and punch the young punk silly.
脑满肠肥indeed.

Another one was a Biology question from XX Secondary School's prelims.
Simple MCQ question that asked

Which of the following shows a plant cell?
1: [Diagram of a neuron]
2: [Diagram of a plant epidermal cell]
3: [Diagram of muscle cell]
4: [Diagram of guard cells]

A: 1 & 3
B: 2 & 4
C: 2 & 3
D: 2 only

Obviously everyone chose option B.
WRONG!!!
Answer is D!

Because the question asked for a plant cell.
Singular! Singular!
Whereas the diagram of guard cells showed a pair of plant cells, so it can't be the answer.

Gee I didn't know it was a Biology cum English exam paper. It'll be funny, if only the students didn't need to depend on their prelim grades to get into JC for the first month. As it is I feel really sorry for my kids. I'm really sorry that their teachers are such screw-ups.

What the heck are the teachers hoping to achieve by setting this kind of question, I have no idea. They seem to be, at least in my mind, flipping the students the bird and gloating "HAH! Didn't expect THIS did you? Can't get past me no matter how hard you study nyah nyah nyah"

*roll eyes*
