You've posted this question multiple times on Academia.SE, and each time, other users asked you to clarify your question. For example, on this copy:
Please clarify what "higher secondary level book" means. – scaaahu Jul 31 at 4:03
and on this copy:
I'm kind of confused by your terminology. What does "completed his/her post-graduation" mean - did this person finish a degree? Masters? PhD? About this result - is this about a thesis that was weaker than hoped? What is a "passive teacher"? – Nate Eldredge Jun 20 at 4:05
You've also posted this question on other SE sites, such as History of Science and Mathematics. There, too, you were asked to clarify the question and didn't. (They tried to migrate it to Academia, but of course it was closed there again.) Same thing on Quantitative finance (!). Google search results suggest you've also asked it on SciFi and Fantasy, Philosophy, Information Security, Freelancing, Open Source and probably other sites as well.
Instead of responding to comments, you delete your account each time you post this question, so that you can't clarify your post.
In its current state this question cannot be answered anywhere. If you want an answer, you should stop deleting your account immediately after posting the question, be responsive to comments, and edit your post to add information that others ask for in comments.
After all that, it may or may not be on topic somewhere in the SE network. (We can't tell right now because nobody can understand the question.) But if you keep posting the same thing as is over and over on all different sites without clarifying it as requested (and continuing to respond to requests for clarification), you'll never know. It will just keep being closed everywhere you post it.
