HOW TO PREPARE IIT-JAM/M.SC ENTRANCE EXAM

Two ­ Tier Admission Process

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

1. 1. JEE ­ Main
2. 2. JEE ­ Advanced

JEE ADMISSION PROCEDURE

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 JEE Advanced 2015 Question Papers will consist of objective type (multiple choice) and numerical answer type questions designed to test comprehension, reasoning and analytical ability of candidates.

Some sections carry negative marking in the JEE Advanced 2015 Question Papers.

The answers are to be marked on the first page of Optical Response Sheets (ORS). The two pages of ORS shall have the same layout.

Candidates should use BLACK BALL POINT pen for darkening the bubbles.

The first page of ORS shall be machine readable and is designed to leave impressions in the second page.

The second page of ORS will be handed over to candidates at the end of examination, which shall have the impressions of the answers as marked by them in the first page of ORS.

There is not any fixed exam pattern for JEE Advanced 2015. Following is the exam pattern of JEE Advanced 2014 and candidates can get an idea from it: Paper Paper 1 Paper 2 Subjects Physics Chemistry Mathematics Physics Chemistry Mathematics

ABOUT CHEMISTRY

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 concepts.

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 concept.

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

1. Mole Concept
2. Redox Reactions
3. Stoichiometry
4. Gaseous and Liquid states
5. Atomic structure
6. Chemical Bonding
7. Chemical Energetics
8. Chemical Equilibrium
9. Ionic Equilibrium
10. Electrochemistry
11. Chemical Kinetics
12. Solid State
13. States of Matter
14. Solutions & collegative properties
15. Surface Chemistry
16. 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 IIT JEE.

Topics covered under IIT JEE Organic chemistry are:­

Basic Concepts

1. Nomenclature
2. Isomerism
3. Reaction Mechanism
4. Saturated hydrocarbons
5. Alkenes and alkynes
6. Reactions of benzene
7. Aromatic compounds
8. Alkyl halides
9. Alcohols and ethers
10. Aldehydes and Ketones

Carboxylic acid and their derivatives Amines 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.
