Am not sure bout law.. But for a level it cost more than 10K for whole course..
Erm... If you mean Hostel.. Theres expensive one cost 2k plus per sem, a very luxurious type to 700 plus per sem depending also whether you choose to stay single room or twin sharing with the same gender.. Single room cost more than sharing one.. And there are guards in front of every block with no curfew. No worries there..
If you wana stay with your gf.. I reckon you stay in apartments nearby.. The price i think you can check in previous posts.. RM 300 to RM700 per month for one unit i think.. With 2 to 3 rooms.. If not mistaken..But just be careful in the apartments.. Its not that safe nowadays..
Overall INTI is a nice place to study.. Easy to reach KL with KTM.. And its not that noisy with allot of distraction.. People are generally nice.. yea..
There are some jobs in the campus.. You can go Job placement office at level 2 to search for it.. Normally its working days and hours only.. The hour of work depends on your timetable.. But normally you wun find the time less you only have one or two subjects per sem..
You can also become a student helper for SAO or any place you can get.. Rm2 to RM3 per hour
Or you can be a floor rep.. RM200 per sem..
Erm, if you really want.. You can also work in a food centre outside INTI at night.. Depending your way of scheduling your timetable.. I have known few who did this.. But they are super good at time management.. And its exhausting.. If can better dun work while study.. Hope it clears abit of your question..
Its always available.. You can ask the accommodation office staff to provide you list of people to contact for any block you want.
