Rajalakshmi, these things might be issues. But just apply to loyola college and other good ones. What is your son planning to do BSc/Bcom/BAA/BA or what ? Plan your college application based on specialization that he plans to take so it helps him in long run. If he is planning to be in Business or commerce he can try DG Vishnav College, Vivekananda Collage, Gurunanak College. DG Viashnav is best. For other streams you need to consult someone and take a decision.
