Admission Process

Two­Tier Admission Process

The Joint Entrance Examination for admission to the undergraduate programmes in engineering is conducted in two parts:




This two tier common test for IITs (Indian Institutes of Technology), NITs (National Institutes of Technology) and IIITs (Indian Institutes of Information Technology) has replaced earlier IIT­JEE and AIEEE from 2013. A composite score is calculated from JEE­Main performance and your class XII (or equivalent exam) marks This score is considered for initial screening.

Weightage to Class XII Board Marks

Now, weightage is also given for the XII board or equivalent marks, though the percentage of weightage varies with the types of Institutes. The board marks are normalized on percentile basis through an appropriate formula.

Admission Process for IITs

For initial screening, a composite score is calculated with 40% weightage to class XII Board or equivalent marks and the remaining 60% weightage to JEE Main performance. Based on this composite score, a fixed number of candidates (1,50,000 candidates) are considered eligible for admission. These short­listed candidates are then ranked in the order of merit entirely based on their performance in the JEE Advanced examination. It is essential for you to gfet 75% marks or figure in the top 20 percentile bracket of your respective Class XII Boards, whichever is lower.

Admission Process for Other Institutes

If you are aspiring to get admission to NITs and other institutes only, then you need to give only JEE Main exam. There is 40% weightage for performance in Class XII Board marks normalized on percentile basis and 60% weightage for performance in JEE Main

The Paper­2 (B. Arch./B. Planning.) of JEE Main will be conducted only in Pen and Paper based examination mode. A candidate will be opting for either the Pen and Paper Based mode or for the Computer­Based examination modes for Paper­1 (B. E./B. Tech.) only.

Candidates may take Paper­1 (B.E /B.Tech), or Paper­2 (B.Arch / B.Planning), or both as per the

courses, they are seeking admission for.

Paper Pattern:

The paper would be of 3 hour duration and there would be two papers.

Paper I would contain Physics, Chemistry and Mathematics.

Paper II would contain PCM, Drawing and Aptitude Test .

Chemistry is one such subject which can assure you guaranteed marks in IIT JEE if you have

prepared well. Most of the topics in chemistry are not very much twisted and get tested directly.

For example most of the students do not pay much attention to topics like:­ s, p, d blocks,

transition elements, surface chemistry, coordination compounds, gaseous state, nuclear chemistry,

chemical equilibrium and stereo­chemistry. These topics are not only easy but do get questions in

IIT JEE Chemistry papers every year and hence are very scoring but still students do neglect them.

Scoring in Chemistry is more about planning than about application and understanding of


Certain topics like organic chemistry are pretty much like mathematics and physics as far as IIT

JEE is concerned as it relies on testing of concepts and questions are always framed considering

multiple concepts together. Unlike organic chemistry, inorganic chemistry is directly opposite as

all questions asked are always direct and do not need much application. Topics like stoichiometry

are always difficult to handle and need lot of in depth knowledge about reactions and mole


It is very much advisable to solve past 10 years(Minimum) IIT JEE papers for chemistry. Most of

the questions are repeated in an indirect manner. This is true for inorganic and organic chemistry

than physical chemistry because in physical chemistry lot of concept testing is involved. When you

solve problems from past years IIT JEE papers of Chemistry, you would see a pattern in which

questions / concepts are tested. In fact with a proper planning you can make chemistry as the most

scoring subject out of all three in IIT JEE.

Physical Chemistry

Physical Chemistry is the branch of chemistry which is quite like mathematics and physics in

developing underlying principles of chemistry. It observes and explains the physical and chemical

properties of matter. Physical chemistry at IIT JEE level starts from basics of mole concept,

quantities at atomic level and covers energy, thermodynamics and kinetics which forms the basis

of how reactions occur. Various topics covered in physical chemistry such as stoichiometry,

chemical equilibrium, concentration of solutions, atomic structure, thermodynamics or chemical

energetic form the backbone of chemistry at IIT JEE level and higher chemistry at graduate and

post graduate level.

Physical chemistry has at least 30­ - 40% weight­age in the IIT JEE chemistry paper and hence it is

most important of the trio – physical, organic and inorganic chemistry.

Topics covered under IIT JEE physical chemistry are:­

Basic Concepts

(I) Mole Concept

(II) Redox Reactions


Gaseous and Liquid states

Atomic structure

Chemical Bonding

Chemical Energetics

Chemical Equilibrium

Ionic Equilibrium


Chemical Kinetics

Solid State

States of Matter

Solutions & collegative properties

Surface Chemistry

Organic Chemistry

Organic Chemistry is the branch of chemistry which deals mostly with the objects in life.

Though, it is not quite mathematical in nature, but the basics of Thermodynamics and

Kinetics are still the underlying principles. It observes and explains the chemistry in life.

Although Organic Chemistry in itself is quite vast but at IIT JEE level it deals with General

Organic Chemistry. It starts with the concept of Hybridization, IUPAC Nomenclature,

Isomerism, Resonance, Hyperconjugation, etc. Stereoisomerism is a critical part which

becomes a bottleneck for most of the students. These concepts are used in almost every

reaction mechanisms which are a part of topics like Hydrocarbons, Halides, Alcohols &

Phenols, Aldehydes & Ketones, Carboxylic acids and derivatives. Named Reactions are like

drivers direction for students and maximum come from the chapter of Aldehydes & Ketones,

which is no less than a climax of a movie.

Organic chemistry has at least 30 - ­40% weight­age in the IIT JEE chemistry paper. It is the

most critical part of chemistry where scoring is important to occupy a high berth in AIR of


Topics covered under IIT JEE Organic chemistry are:­

Basic Concepts



Reaction Mechanism

Saturated hydrocarbons

Alkenes and alkynes

Reactions of benzene

Aromatic compounds

Alkyl halides

Alcohols and ethers

Aldehydes and Ketones

Carboxylic acid and their derivatives


Carbohydrates, amino acids and peptides.

Uses of some important polymers.

Inorganic Chemistry

Inorganic Chemistry is the branch of chemistry which deals with the chemical changes in

most primitive manner. It is not mathematical in nature and deals in elemental form of

nature. The Mendeleev’s Periodic Table becomes the basis of study as we divide the

elements according to their groups and then study them. These groups are regrouped as s-
block, p­block, d­block and f­block elements. In these p­block is not the bulkiest but also the

most important part. The order of importance is followed by s­block elements. The chapter of

Coordination Compounds is also important from the scoring point of view. The other

chapters of Analytical Chemistry and Extraction of Elements also fetch few questions which

are direct in nature.

Inorganic chemistry has at least 25­ - 30% weight­age in the IIT JEE chemistry paper.

However, if we talk about the effort to scoring ratio from IIT JEE perspective then it is the

least in this case. A good student cannot afford to ignore this section.

Topics covered under IIT JEE Inorganic chemistry are:­

Basic Concepts

Extraction of elements


S and P Block Elements

d and f­Block elements

Coordination compounds & organometallics

Qualitative Analysis
