• # Analysis of JEE Main 2013 Paper 1 | Expected Marks for JEE Advanced

The dust seems to be settling now as far as the JEE Main 2013 is concerned. A few thousand students are expected to take the JEE Main online version today but for most it is now time to re-evaluate where they stand vis-ŕ-vis marks and whether or not they must prepare for the JEE Advanced at all.

Before we move on to what the expected cut off for JEE Main is going to be, let us first analyze what the JEE Main was all about. Here we delve in to the depths of the paper and try to understand where you could have scored and where there were chances of faltering.

PHYSICS

Overall Marks Distribution
Class 11: 48 marks
Class 12: 72 marks

Difficulty Analysis
If, 1 was Easy, 2 was Moderate and 3 was Difficult, then Physics as far as we are concerned had a difficulty level of 2.10.

There were a total of 6 questions of high difficulty with 8 questions being moderately difficult and only 16 questions were easy. A weighted average tells us that the difficulty level was 2.10.

HOW MANY MARKS ARE REQUIRED TO QUALIFY FOR JEE ADVANCED?

Our team of experts suggest that this year, because the level of difficulty was not much, the cut offs will certainly go up. Also, the number of students taking the exam has increased significantly this year and hence the competition will be even more intense.

To qualify for JEE Advance, we feel that a score of at least 100 will be required to get a rank under 150,000. We have tried to come up with a fair estimation of what could be the probable ranks vs the marks that students get in the table below. We are reasonably sure that this pattern would be followed closely when the result ultimately comes out.

 Aggregate Marks Expected Rankings 340 1 301 501 280 1001 270 1501 261 2001 252 2501 231 5001 215 7501 201 10001 191 15001 181 20001 173 25001 165 30001 155 40001 145 50001 125 100001 100 150001
