At that rate (70%) potential students should opt not to pursue higher education instead. Anyhow, I do agree with the stats that Comp Sci and IT grads are by far the biggest number of unemployed graduates. This is in accordance with the Internet boom of the late 90's / early 00's. Hence the high number of intake in such courses during those times. And the spill out is evident now. Besides, entry requirements are usually lower than other applied sciences, even at good foreign universities. So post-SPM students at the time enrolled en masse for these programmes that they think could provide them with lucrative jobs. But, they were sorely mistaken when reality kicks in after enrolling.
Computer science is a highly technical area. A student must have strong logical thinking and be able to understand problems quick. A strong mathematical foundation is required. Many students, and I believe the weak ones especially, thinks that computer science is all about "messing around" with computers with a bit of programming and so on. An easy job where one dresses smartly, and runs around meeting clients.
As many have pointed out, there is no shortage in demand of IT professionals. It all boils down to the attitude of the graduates that's causing this high unemployment rate (for IT). Skills mis-match and technical inefficiencies can be adressed, they can be taught and learned. The difference is in the attitude. Of course, this only applies to IT and similar graduates (e.g. Engineering). Some areas like Biology, Chemistry and Polymer Science have their fair share of unemployment, but that's cause of the lack of jobs in their industry.
