mummy so kiasu:

Hi, Any one know what is class achievement award? Is it given to the top 3 students in the class?

I think is given to top 5 students in each class. My girl's class has 5 students awarded class achievement. They are based on their overall marks.

May I check when will we get to receive the orientation letter and booklist for P1 2017? My friend’s daughter from another school has already received the letter cum booklist this week.

Thanks! EconsPhDTutor
