The dumb main stream media again

See this news item. Here is what the article claims.
Gourav Bhattacharya of Mumbai knows how to bell the CAT. He - like only 10-odd other management aspirants all over India - has scored a 100 percentile in the entrance examination to the Indian Institutes of Management.

I am not an expert in calculating percentiles, but I know couple of things for sure. When scores are represented as percentiles, there would be always one person who gets the top percentile.

I am not even sure that anybody can get 100 percentile. As per the percentile rank definition from wikipedia
The percentile rank of a score is the percentage of scores in its frequency distribution which are lower. For example, a test score which is greater than 90% of the scores of people taking the test is said to be at the 90th percentile.

As per above definition, one can not get 100 percentile because that would mean that your score is greater than the score of 100% of the people taking test, that would be impossible because you are also part of 100%.

The dumb main stream media

Here is another stupid media headline. Here is what the headline says.

This is supposed to be the largest mainstream daily for English news in India. I think we really need a new news paper.
