well there is quite a number of students that travel on daily basis, esp the living cost staying on campus is high, plus stay offcampus is a bit boring + danger. well is really depend on you, if your course timetable are being divide nicely, like one week 3,4days got class, then most of us will just travel, stay home more better. me even got one fren come uni for 2 days onli, cos dunno the admin how to divide course, all campur in 2-3 days (the third day only got one section of clss, so he just skip it, only come when necessary)

well for your case, 50minutes is still acceptable, but did u include the traffic jam time ? cos the way from kajang to semenyih always traffic jam at peak hours...will make you late for class, sumtime even lecturer also late for class ...

just be careful when stay at TTS area. Dun ever try to walk back alone at anytime. Cos previously there are a lot of case either reported/non-reported happened before. even stay in hostel also dun take for granted that the security guard will do their duty well, sometime even the food in the refrigerator will gone missing. There was also several case that laptop missing in the room.
