well if u feel u no dungu then u're not. :|
i feel there are a number of students seems too detached from society.
of the 3-4 years of your study, why not make the most of it and be socially active? of cos it's again personal preferences of course. all in all i can at least say I very well enjoyed my 4 years in UTM and made the most out of my time instead of just studying.
the sports centre is quite well equipped IMO. the gym is quite good too, only tht the equipments are a bit old, usable nonetheless. shit sux cos a lot of ppl after using them they don't take care of it.
but if u wanna go gym, best to avoid 4pm onwards, cos that time will be crowded. Best time is u go at 3pm. u have the whole gym to yourself

there are a number of of tennis/badminton courts in UTM. there are also several indoor badminton courts around. usually it's fully used in the evenings, but u could always use it at night.

and no, there's no court that's specific for seniors. all students are equal. certain courts are managed by colleges or sports office. so to use it u would need to book to avoid gaduh2. so book ur games early .

what do u meant by taik..
is it the quality or is it old stuff??
