I've 50% in honors subject but 48% in aggregate subjects. Now, I'm working as a teacher & have 1-year teaching experience. What should I do?

If you want to be a school teacher, you have to do B.Ed. /D. Ed. One more thing, you have to checkout for minimum percentage criteria because your are out off from unreserved minimum percentage criteria.

If you want to be in teaching domain, then it would be better to continue your studies and pursue B.Ed and that you can do through correspondence.
