Eh... your chances of appealing practically ZERO...
I would suggest if you are really interested in going to a poly
(since you practically failed for the past 16-17 years based on
your results), then please work harder and retake your O level. It
would be hard since no one is tutoring you, but if you still
remember what your teachers taught you and then work on from there
by yourself, put in maximum effort, keep practicing and practicing,
you will be able to make it. You can study in ITE and revise for
your O levels simultaneously, if you put in effort.
Otherwise, you can go to ITE NITEC and then work hard from
there. Going to ITE does not means its the end. ITE in fact has
many outstanding students and some of them are just as successful
as those from poly and uni, and maybe even more successful. IF your
results are good, then from ITE, you can move to Poly and then to
Uni. The only turn off of this route is that you take longer than
others. But it is still a route for you, and if your are determine
enough, you can still succeed.
Therefore, since you now probably regret on not studying for
your O levels, and getting this type of shitty results, I seriously
hope that you would reflect on your past actions and think about
what have you achieved in life so far. Do you really think that all
the playing and fooling around in the past is worth it given the
situation that you are in now? If you have seriously understand,
then I hope that you will buck up and start working hard now. It is
never too late to start working hard. You can do it, you have to
help yourself!!
