Ms Teh from Leaping Science did an experiment in her tuition class to explain the concept for THE balloon question (seems to be one of the toughest questions). BINGO!


According to my girl, Ms Teh is "awesome", kind & encouraging, always telling them "Just try your best!". I think the little experirments they do in class helps explain the concepts well.

And yes, science paper seems to be the toughest paper this year.
