Wonder Why Selected the subject he does not like

My nephew is studying in his hometown now. He has a girlfriend staying in our area, therefore he would stay at our home every time come to visit his girlfriend. I do not think he is good in his study now because I know that is not his favorite subject. I thought he would enroll into medical assistant training school previously.

He told me before he wish to be a doctor or any related vacant. His result wasn’t good; therefore it is impossible to be a doctor. But I thought he would be interested to be a Medical assistant. Well, I am wrong, he enroll into a business program which I think it is not his favorite subject.
