Hi Muthu,
Not every institute conducts entrance exam for UG course in economics. Most universities consider the 10+2 score for admission. Others that conduct entrance exam, will determine the admission on the basis of an aptitude test. Basically, the student should be well-versed with economics taught in 10+2 along with maths till 10th standard. Current affairs are equally important.

There is no such standard course for the highest placements in India. It depends upon which college you get into & as per the market standards & requirements.
