timetable depends on which class u're in. and which lecturer is teaching u. some classes have class on saturday. interior design there is not bad. eric leong is teaching there.

It depends most of the time, not sure about interior design, but for other courses where there are more people taking it, there're usually 2 classes, so one class will be in the morning - afternoon, the other in the afternoon - evening. Or sometimes, full day. I currently have a class till 10pm.

Usually only 2 classes a day, or 1.

Yes, there will be LAN subjects, it is compulsary in every college/uni in Malaysia, you can't escape from it!
