i don't really have any ways to help u in getting into a
poly.
but i can advise you that don't ever give up. i got one friend
who failed her maths, so she ended up in ITE. However, she was
determined to get into poly. So she retook her maths and some other
subs while studying in ITE. and guess what, she did well in
retaking her o's and now she's accepted into np and into her
favourite course somemore.
And another advice is on how to study english. I HIGHLY
recommend you to read more. it's very important. no time borrow
books, never mind one. There's always the newspapers to read. I
make it a point to read the newspaper every morning without fail.
Do not just read soccer news. If u hate reading news that are
irrelevant to you, try reading HOME. It consists of whatever is
happening in singapore.
another way to improve english is to definitely speak it more!
speak it whenever u can! trust me it helps. and for me, because i
consecutively failed chinese in my school exams, so i started to
listen to mandarin songs, and i even learn to write lyrics of jay
chou and guess what, i scored a B3 in my first attempt taking the
chinese o levels.
so never give up, it's never too late to learn your
mistakes.
P.S just don't waste ur life anymore. I have friends who failed
maths and went into a sucky course in other school, and now drop
out of the course and doesn't know where to head. Plan ur future
wisely.
