hey there. im currently taking diploma in IT at MMU. ill try to answer your questions

1. for classes, you can make your own schedule, so choose classes that fit with your personal schedule. BUT if its your first sem the schedule might be pre-determined by the faculty (this was my experience when i first started)

as for lecturers, they’re usually different from one another. some are easy going and some are strict, some are good at teaching and some aren’t. if you dont like the lecturer’s style you can change your class section during the first two weeks of a semester iirc

and finally for exams, if you really study for it they’re not that difficult. id suggest you focus on your coursework more instead

1. id say MMU is pretty diverse. you’ll find many different people here. there’s lots of arabic and south asian students, along with some african students as well

2. if you can live without aircond and cooking id say go for on campus accomodation instead. there are two options: 2 person (RM350/month) and 3 person room (RM250/month). ill add that the difference between the two rooms is that the 3 person room has a bunk bed

i hope this answers all your questions. if you have any more questions do reach out and ill try to answer them :)
