JEE Main 2014 paper was conducted in offline mode on April 6th, 2014
Following the usual trend, chemistry section was easier as compared to maths and physics section.
The paper was overall a bit lengthy and calculative however it was easier than JEE Main 2013.
Chemistry : This section was the easiest. There were very few difficult questions. Most questions were directly picked up from NCERT. An average student can easily score above 80-90 in this subject.
Maths : This section was slightly tough and calculation demanding. Those who are aiming for top ranks should score not less than 100 in maths. If a candidate is cautious enough to avoid silly mistakes, then he/she can even score 120/120 in maths.
Physics : This section was the toughest. Those who didn't prepare well were bowled. Paper required calculations and was indeed conceptual. There was a large portion from Mechanics.
Overall : Those who have scored above 270 are likely to do well in JEE Advanced too unless they mess the paper. 300+ is outstanding. The highest marks are expected to go down (as compared to 345 last year). However, since the paper was simpler, the cutoff might go slightly up. The inclusion of Board's marks will have a significant effect in the ranks of students.
Those students who are aiming for an under 100 rank in JEE advanced should score not less than 300. Note that if your score is less than 300, then it doesn't mean that you can't get an under 100 rank in JEE Advanced. Take it the other way, if you have scored more than 300 in JEE Main, then it doesn't mean that you will get an under 100 rank in JEE Advanced.
If you performed well, then take it as an achievement and let your confidence go sky high. However, if you couldn't perform well, then don't panic. JEE Advanced is very different from JEE Main.
Even I couldn't do well in physics in JEE Main 2013 but that does not mean that I was weak in Physics. So keep calm and continue preparing for JEE Main.
PS : Please don't post comments regarding cut-off etc. I cannot give any comments. All I can say is that cut-off might be around 125 (That's a guess)
Also, I have no idea about rank v/s marks distribution for JEE Main and lastly, no comments on rank v/s college (NIT etc)
