For a teacher to teach in any school, it is necessary to have B.Ed. According to my opinion, B.Tech+M.Tech didn't have any relation with B.Ed because I have a friend who is pursuing MA English now and her course will get over this year. I asked about her plan after this and she told me that she is going to take B.Ed so that she can work as a teacher in any school.

school as a teacher.

60,000 per year is the fees and the total amount will be 1 lakh 20 thousand for structural engineering in M.Tech in management quota.

Else, you have an option of part-time. You have to attend weekend classes, but the examination will be conducted any day.
