Dear Ashok, you havent mentioned the State and Category you belong to. With 178 marks, it is highly impossible for a seat in any Government Medical College. You can try in Deemed/Central Universities after the mop up round of All India Counselling. The vacant seats will be transferred to respective Universites and they conduct mop up round for remaining seats. Or the other way is any left over seats after all rounds of Counselling will be transferred to the respective
Medical Colleges and for them you can directly contact the respective Private Medical College for direct admission. But with a score of 178, a seat through counselling is not possible. If MBBS is your son's goal, this might help him:
