1. Yes, it's in the Design & Manufacture where you will learn how to draw engineering parts via Pro|E, a CAD modelling software. In Year 2, you'll be taking up modules for MATLAB, a mathematical computation software whereas in Year 3 and 4, depending on the electives and projects you do, you'll need different types of software. In Mechanical department, all our lab reports are to be produced electronically, so do many other writing assignments. As a student, you'll get a student version of Pro|E.
I see I see. Guess I have to go laptop hunting now.
Extra cost
2. It all depends how many students apply and how many places are there to be filled up. I was told there's about 10 seats available 2 years ago, per school, and it doesn't seem that people are all going for it. Be aware that the student population grow very steeply within these years and I can't tell if it's at your batch, what is going to happen. My year, it's about whether we want to or not because there are excess of seats for Mechanical.
That's seems promising. 
Really hoping to at least spend a year overseas for my tertiary studies.
3. Start Sept 2011, finish Year 1 by May 12, Year 2 by May 13, Year 3 by May 14, graduation somewhere in July 2014. Wait, I thought the world ends at 2012?
The world was suppose to end at May 21, 2011. But it was postponed to October 21, 2011.
4. After you join the university, you'll receive emails about that. I didn't apply PTPTN, so, some other may have better info for you about this.
Wah, didn't apply? You are either on scholarship or very rich.
