ALRIGHT!
I'VE GOTTEN POA!
but what i don't understand is the Based on your math's results & teacher's recommendation, you are eligible to read O-level Mathematics & N-level Add mathematics.
can anyone explain to me? thanks!

edit! 1.42pm

Wong Lai Fong (teacher) : You've indicated in your online option that you wish to take N-level Additional Mathematics. N-level AM is offered together with O-level Math, which means that you will sit for O-level Math when you are in Sec 4. If you do well in that sitting, you need not take O-level Math in Sec 5 and can just concentrate on your remaining subjects. Should you be not satisfied with your result, you will may again when you are in Sec 5.
