if no friends in JC, there are two possible reasons:
1. you are the only one in your secondary school clique that
goes to the JC you are in.
2. you are all along a loner.
If it is the first reason, no worries, gradually, you will have
friends.
If it is the second reason, it is very likely that you are also
not that kind who likes to talk. If so, I recommend that you train
yourself to talk, either in front of a mirror, or in front of a
camera (film yourself talk). Because not only does it enable you to
socialise, the oral exams you take depends on it too.
if go JC, means
have to go to university after that, otherwise with just that A
level certificate, it's not going to get you anywhere (or limited
options).
Now at JC, you
only have project works and oral
examinations. Next time go University it is
going to be even more challenging if you still continue to have no
friends.
