I suggest you to try to apply for the local Uni now to test
water. Assuming is never a good thing, especially when it comes to
SAF, heard of the pharse "You think, I thought, who confirm?" ?
I have already seen ppl who aim high but in the end get
disappointed. Aim to be officer but can't get in. Or get into OCS
but buang the course (gets injured, fail physical, etc). Think can
get scholarship but in the end fail to get into Uni due to poor
grades (not in sense fail grade but the competition is just too
strong that you are out of the selection circle). Or get into Uni
"ta pao" too many times and buang Uni, espically those from poly
route who cannot get used to the Uni lifestyle. etc, etc.
All I can say is be mentally prepared that when you sign on, you
will end up as a specialist and can't get into Uni, this is not
throw cold water at you because I also want to see you succeed but
just be mentally prepared that you might not get what you want.
Especially in the SAF.
