I would say "yes, you should take". I think you think too much, a lot of people think it'not worth it working with government. In my opinion, I think they think too much, because now or even in future , it's not easy to find a job outside. Since, the govenment will offer a job for you..and why not?
Also, you will finish your studies without financial problems.It's really great , you know. You are really lucky if compared to others.
Last time, I also think too much as you, so I didn't give it a try. that is I didn't apply. I feel regretted now. If i were you, I wouldn't let it happened again.
I am currently waiting for my STPM result, although there's no more JPA scolarship , I think I would try all other scolarship that offered to STPM students.
