Which course shd mu son do if he get 48% in 12 sicence?
All the courses are equally good and there are immense opportunities in every field. But the most important factor to conquer any field is interest.
So I will suggest you, to choose the course in which he is interested, then only he will be able to give his 100%.
Though marks are important, but do not choose your career on this basis.
Your son's marks are enough to get admission in good private colleges.
Hope this helps,
Regards!
