The cutoffs in each subject and the marks obtained by the topper and the last candidate in JEE 2009 has been announced. The Minimum Qualifying Mark for Ranking in chemistry, mathematics and physics (out of 16o each) is 11, 11 and 8, respectively. The overall cutoff to get a rank in JEE is 178 (out of 480). The website mentions that the overall cutoff is 178 out of 160, which is ridiculous. The tables should have been checked before being published.
Rank 1 scored 424 (out of 480). Rank 501 scored 302. Here is the graph showing that the difference in marks between 5000 and 8000 is minimal.
