Hello Mr. Krishna Arandhara,
Kindly follow proper punctuation in your contributions.
1. You should leave a space between two different sentences. Hit the "space bar" once after each full stop (.) for proper punctuation.
2. You should write abbreviations in CAPITAL letters. E.g. I. S. or IS
3. While you are using the full form of an abbreviation, you should start every word with a Capital letter. E.g. If you are writing full form of IS, then you should write "Inspector of Schools", instead of "inspector of schools". So, I hope you will follow these punctuation rules in near future.
