Dear Fakhrul, 

I understand your point. Commerce has earned trust of students to achieve their career easily and at the early phase of their life. This might me a major factor here.

In primary school, pupils often have a strong curiosity for science items, but courses often focus on knowledge and facts rather than on understanding. At lower secondary school level, pupils need to feel the relevance of the subject to their own world. This is far from being always the case, and what is taught is often disconnected from cutting edge science. At upper secondary and tertiary levels, S&T subjects have to compete with new subjects. Furthermore, students prefer courses that open access to the job market at various stages, which is not the case for some of the S&T traditional curricula. Science subjects are generally considered as difficult and there seems to exist a general perception that it is much more difficult to obtain good grades than in other subjects. Young students are unaware of the range of career opportunities opened by science studies. The professional integration process for young scientists is long and difficult in academia, which is still perceived as the gold-standard for scientifically-trained students. Incomes in S&T careers are often perceived as too low relative to the amount of work and difficulty of the studies required.

Dear Sir, a simple example - the best Neurosurgeon works in a hospital and end of the day the day most of the medical center stake holders and share holders and owners are RICH business people who have good commerce knowledge.

I believe today's world have the money to buy any skill you want than to be skilled to the best but still you are not the person to control commerce trade and other business artifacts. Thanks

That is true especially in the USA. Achievement scores in science and math aptitude tests show that nationally. "Among the 35 members of the Organization for Economic Cooperation and Development, which sponsors the PISA initiative, the U.S. ranked 30th in math and 19th in science," as per a Pew Research Center Report https://www.pewresearch.org/fact-tank/2017/02/15/u-s-students-internationally-math-science/ . Science and math are harder subjects and many students are taking the easy approach by going into other areas including humanities, liberal arts or commerce. It is exactly the opposite for students in S. Korea. They spend more time in school, spend an enormous amount of time outside school studying school-related matters and are very hard working. When President Obama returned to the USA after his visit to South Korea, he shared that information with the professionals here who were quick to ridicule him saying that the Korean kids study by rote memorization. There is nothing wrong with rote memorization to get the concepts in. Many of the US high schools kids don't even remember the simple times table (math multiplication table!)
