if u are asking this question, u are already asthmatic?
officially in your medical records?
if this being the case i doubt u will be graded pes a or b, more
likely pes c. in which case you wont be going ocs.
and even if its a mild case, and u get pes b, are u sure u'll be
able to cope? ocs is not all classroom and lecture u know. someone
mentioned u onli need to pass ippt and dont need to pass soc. true,
but once inside, u must get at least silver for ippt and must pass
soc to stay in, else you get ooc. and anyway, soc and ippt will be
the least of your worries where physical demands are
concerned.
i'm not tryin to dampen your spirit. i just think its pointless
tryin to get one's hopes so high up, especially if as u say NS is
still a long way off for u. there is no proven method to get in.
either u have wat it takes, or u dont.
