What do I must do in order my rating to be increased????????????
You need to solve more problems at contests.
even I solved 2 problems at CODERSTRIKE ROUND 1 my rating has decreased again... why??
Your rating depends on your rank in a contest. To maintain pupil status you need to solve at least 2 problems in a regular CF round. But since the last round was easier than the rest you should have solved 3.
Also the speed of coding these 2 problems is important factor , many people solved the same problems as ou but since they were faster they had better rank than you
The negative contribution value comes from writing annoying and badly researched questions like these. Maybe try to avoid those in the future and read the documentation instead.
Double posting is highly frowned upon too.
