We certainly need more no.of IITs.The argument that more no.of IITs dilute the quality is true then to improve the quality lets have only one IIT?But that cannot be the case .Premier educational institution are cannot be called so if they take the best people in the country and take credit for their performances.If they really have the quality they should be able to take an average student and make him the best.Above all its nations responsiblity to provide us with the best education .These institutes should cater to the needs of the nation.Whats the use if your premier institute can take only 4,000 odd students when the people competing for it are in lakhs.Is it not unfair?Atleast they should be able to catre to 40-50% of students.
I say more no. of IITs will not dilute the quality because aftre entering IITs let them have their strict evaluation and let them give the degree to only those who clear their tests and match their performance standards.This makes the competetion fair rather than keeping people away from the IITs.
Even before you take the students into IITs you talk of quality which is unfair.The institutes are there to teach them and make them better.
