Tips for MathematicsTips 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 & DeterminantsAmong 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

Note : No subject should be repeated
A Percentile score of a Candidate in a Board or JEE (Main) will reflect what percentage ofCandidates have scored below this Candidate in that Examination

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 Mainacross 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 forJEE 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) pattern The normalized Board score of the student Bfinal = 0.5*(B1 + B2) [ 0.5*(48+80) = 64 ]
The composite score of the student is C = 0.6*A0 + 0.4*Bfinal [0.6*144 + 0.4*64=112] C is Cumulative Normalized Score of this candidate. This score is used for preparing merit list.

Appendix 2 : Rank Prediction from Table 2Appendix 2 : Rank Prediction from Table 2
Cumulative Normalized score for Soham is 135.2 . It lies between125 and 150. His rank can be predicted using linear interpolationmethod.
Soham has 10.2 marks greater than 125. This lies in range of 125 to150 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
