Points to keep in mind •  JEE Mains scores are strong drivers of your future

prospects •  Trend analysis of performance of students in JEE

Mains - 2013 as well as the paper pattern over past 5 years suggests some basic facts

•  These facts are worth sharing with all the JEE Mains 2014 aspirants

•  Scoring 50% or more in JEE Mains can be a piece of cake with some smart efforts in studies

Tips for Mathematics •  Almost 1/3 paper is covered by 4 groups of topics with 2 topics in each i.e.

•  Probability & PnC * Binomial Sequence & Series •  Quadratic & Complex * Matrices & Determinants

Among these 1&4 are largely part of 12th syllabus and can be done with little efforts & can fetch almost 15% of the marks

•  Straight line and Circle have approx. 10% weightage with circle being major contributor •  In conics ellipse should be given time as hyperbola has been largely absent

•  Differential Calculus is expected to have weightage of 20-25% with good portion being covered by Set, Relations, Function & Graph

•  Vector & 3D comprise 10% weightage and they are easy topics •  Trigonometry weightage has increased over the past few years, and is

expected to be 10% in the coming paper with majority from trigonometric ratios and identity

•  Integral Calculus has seen a constant portion of approx10% divided into definite, indefinite and Area under the Curve


Improve Your Rank in JEE Mains •  “Its never too late to begin”. Late starters can still think and

plan for good JEE Mains Rank.

•  Based on the analysis of last 5 year’s papers we present a revision plan that prioritizes the topics in accordance to weightage in JEE Mains and can cater to your specific needs

•  You can pick a plan according to your own expectations, based on your current performances

•  A close introspection suggests contribution of Standard 12th syllabus in JEE Mains is more than 55%.

“Performance is always guided by practice”.

A0 = Aggregate score of a student in JEE-Main [ suppose 40% i.e. 144 marks]

B0 = Percentage score of that student (in five subjects) in the Class XII Board Exam [suppose 60 %]

PB = Corresponding percentile of the student in the Class XII Board examination [calculated 50.07]

Scores B1 and B2 are computed from PB using table 3 and table 4 respectively

Calculation of B1 = Corresponding Score in JEE Main(for all the students appeared in JEE Main across all the Boards) for the percentile PB (50.07) i.e. 48 Refer Table 3

Calculation of B2 = Corresponding Score among the students who satisfy the eligibility criteria for JEE Main and belong to Board ABCD, for percentile PB (50.07) i.e. 80 Refer Table 4

These scores (B1 & B2) helps in normalization of Boards Marks as per JEE (MAINS) paeern ü  The normalized Board score of the student Bfinal = 0.5*(B1 + B2) [ 0.5*(48+80) = 64 ]

ü  The composite score of the student is C = 0.6*A0 + 0.4*Bfinal [0.6*144 + 0.4*64=112] ü  C is Cumulative Normalized Score of this candidate. This score is used for preparing merit list.

Appendix 2 : Rank Prediction from Table 2

•  Cumulative Normalized score for Soham is 135.2 . It lies between 125 and 150. His rank can be predicted using linear interpolation method.

•  Soham has 10.2 marks greater than 125. This lies in range of 125 to 150 marks slab. AIR varies by 31000 for 25 marks in this slab.

•  AIR Variation for 10.2 marks =

•  So AIR of Soham at 135.2 marks would be = 65000 -13000 = 52000 •  Similarly State rank of Soham would be = 5500 – 1020 ≈ 4500
