Been marking scripts of Form Five Students' English essays. Really bad. Don't know when they'll be writing competent enough essays! Makes me sick!
The formats been given a hundred times but no improvement. Talk about language, dead gone. And using expressions, no way!

Why can't my beloved students use expressions like these!!!
