I am on Hwa Chong alumni's mailing list, and this sentence among the messages stood out:
"Okay I'm not sure if there are any current students here (probably there are but they may be busy studying for their Promos/Prelims already..) "
Right. If he just said Prelims, it would have made sense. But if i dun remember wrongly, promos actually start on early October. It is now mid-August... hmm... talk about being kiasu. This guy really is kiasu.
