7. ENTRANCE EXAMINATIONS: INIQUITOUS INSTRUMENT 95 Vol.15, 1979, pp. 93-101. In this paper the correlations "between selection test scores and the first year scores are cited as evidence of appropriateness of the tests. The 'r' values range from a low of 0.23 (general knowledge score vs I year score) to a high of 0.43 (test score in maths component vs 1 year score). The fact that during the 1 year very few engineering courses are taught, as well as the observation that the correlation coefficients are less than 0.5 do not seem to support the author's premise about the validity of the tests. According to one study, nearly a third 6f the alumni of IIT, Bombay, who graduated between 1973 and 1977 have settled abroad. In more than 70 per cent of the cases the purpose of the initial visit was for undergoing further studies. See S.P. Sukhatme and I. Mahadevan, 'Brain Drain and the IIT Graduate', Economic and Political Weekly, June 18,1988, pp. 1287-88. 8. The tremendous popularity of the coaching centres is seen in the multi-crore business transactions of these centres. M.

Vijayasree, 'Psychological Maturity and Motivational Profiles of Management Students', Technical Report, Indian Institute of Management, Ahmedabad, June 1976, p. 22. 'The students of those management institutions group and the fact that they are selected by IIMs is an indicator of their high ability'. The observation can equally apply to those who get selected for IITs. The authors go on to point out that the effects of such a self-concept 'are revealed through their high aggression, dominance, low respect for authority, high ego-achievement, high exhibitionism, high fantasized achievement, low interest in humanities and social sciences, high narcissism and low objectivity'. 10. Vengateswara Roa & Vijayashree, (op.cit) also suggest that 'it may be advisable to select students who are likely to indicate different profiles. In this connection it is also to be noted that the Madras High Court suggested that a more comprehensive question paper for the entrance test be evolved 'so that the candidates who had studied various disciplines of vocational courses would be able to prove their proficiency in general knowledge and aptitude and one of the related subjects (mathematics, physics and chemistry).'
