Most student do not know what is their field of interest  and we guardian not only choose subject for them but force them. Let's not use the word "easy subject" because only  interest makes subjects easy.
One of my nephews was interested in computer; he used to claim that he can hack email. But he was forced to take biology to be a doctor. This is the dilemma, he failed in couple subject. Who is responsible, the boy or the Guardian?
