I don't hear any hiccups in present grading system of CBSE. Is there any news or any flaw found in the grading system?
Anyhow in my opinion re-introduction of Marking system in examinations of CBSE would definitely create more competitiveness amongst the children as well as schools within CBSE. The same may lead to some chaos as 1/2 mark would also play a pivotal role in securing place in further studies and competitive examinations. Because of this marking system, education would definitely be on the commercial side only and it will pave a national highway in commercialisation. Whereas in grading sytem, A+ or A grading would be secured by some group of the children and they will not feel any discrimination amongst themseleves in intelligence. It would lead to form a team or group to carry out further studies together. But in marking system, if a child gets 1/2 mark higher than the other one who is also equivalent to him in intelligence wise, child who get 1/2 mark higher would not be ready to share his thoughts and actions with others.
Therefore, I feel that grading system is better than marking system.
