My last post discussed the actual marks obtained in GATE 2009 and the corresponding percentiles for several branches of engineering. My colleague, Abi, collected the data for metallurgy and posted it. Here it is (percentile-marks)
These marks are generally higher at every percentile level compared to chemical engineering, mechanical engineering, electronics and civil engineering. Let us look at another major branch, electrical engineering,
The difference in the distribution of marks is obvious. EE is much more closely clustered than Chemical and mechanical, which are closely clustered than metallurgy. A mistake in one 2 mark question will set you back by 2.66 marks from the candidate who answered it correctly. Thus a large distribution of marks is desirable. Setting a paper like EE where scoring 22 marks lands you in the 92nd percentile is not good for separating the good from the excellent students.
Both my colleagues who set the EE paper and MT paper, respectively, are good friends of mine but let me go ahead and congratulate the colleague who set the MT paper and achieved a good distribution of marks.
