Where am I not getting it right?
I need orientation from senior colleagues here.
Merit shouldn't be your target but how to learn and contribute meaningfully to the forum. This is because you will get enough merit if your post answers a question, add value or bring something new to the forum. Don't restrict yourself to one or two boards, because with a dedication to learning you can contribute to more boards. You have come to a school, so learning is the first and last rule.
