welcome back 
what you want to know about the engneering? Give me something to start

lectures mainly are good and some are hard to understand. It depends on how fast you can catch the main points of the subject. When lecturer say "important" then you should concentrate harder as it might out for final exam. BTW, the only tips you will ever get is "study all"

Mechanical engineering is at melaka campus. It have all the basic necessity and sufficient for the entire course. I wont say MMU have the best lab as there other university which have better facilities. Try searching Faculty Of Engineering and Technology (FET) and look around the website

University is a place where u gain education and not a place offer employments. If there a university which can guarantee employments for all its graduates, i would also like to go to that university
MMU have quite a reputation on inter-varsity automotive competition. Shell Eco-Maraothon, Inter-university Grandprix etc etc

based on normal circumstances, yes
