Try not ponteng, if feel sleepy also go there sleep, as long as YOU ARE THERE and get the attendence.
Ponteng also got technique one.
i) get someone sign for you, if can
ii) dont do CONCENTRATED ponteng on one subject. Like u have 7 subjects, each u ponteng 20%. You still can get As for every subject.

concentrate well on ur last few weeks studies before exam. get some smart ass coursemates, always ask them when u tak tau ia cakap apa benda.
you can do it de.. 
your parents are not wasting money lar..

Think like this:
i) I LEARNED TO DOTA SO THAT I CAN TRAIN MY EQ NOT TO SCOLD TEAMATE NOOB/OR BEING SCOLDED NOOB.
ii) I SLEEP MORE SO I CAN HAVE HEALTHIER LIFE.
iii) I AM HAPPY RIGHT NOW AND MY PARENTS ARE SURE HAPPY TO HEAR THAT.
iv) I INVOLVE IN MANY ACTIVITIES, SO THAT I KNOW WHAT TO DO WHEN I AM OUT OF THIS SCHOOL. THIS IS WHAT NERDS WOULDN'T LEARN AND THEY MAY GET PISSED OFF LATER.
v) I HAVE DONE MY BEST PART TO THE ACTIVITIES AND STUDIES. I AM NOT SOME IDIOTS WHO GO PUBS EVERYDAY AND SPEND NIGHTS ON PPL'S BEDS.

Chins up!
Be happy to what you are having.
That's the best present to your parents.

(I am having my 2 months holidays right now so I HAVE PLENTY OF TIME to luo suo.. MUAHAHAHAHAHA.. when back ar? I and kl go find you? muahahahahaha)
