1. Performance in JEE-2010 The answer paper of JEE-2010 is a machine-gradable Optical Response Sheet (ORS). These sheets are scrutinized and graded with extreme care after the examination. There is NO provision for re-grading and re-totaling. No photocopies of the machine-gradable sheets will be made available. No correspondence in this regard will be entertained. Candidates will get to know their All India Ranks (AIR) /Category ranks through our websites/SMS/IVRS onMay 26, 2010. Candidates can view their performance in JEE-2010 from JEE websites from June 3, 2010. 2. Ranking Only those candidates who attempted both Paper-I and Paper-II will be considered for the ranking. Marks in Chemistry in JEE will be equal to marks in Chemistry section of Paper-I plus marks in Chemistry section of Paper-II . Similar procedure will be followed for Mathematics and Physics. The sum of the marks obtained in the individual subjects in JEE will be the aggregate mark for the candidate. The average of the...
