                TIPS to Success in IIT-JEE


1)  First prepare yourselves mentally for IIT-JEE

 "The success is to be achieved", keeping this in mind the aspirants must accept themselves as deserving candidates for JEE success because during preparation confidence plays an important role. Be Self Confident, I would like to cite a quotation of Mahatma Gandhi,

                            "Men often become what they believe themselves to be, if I believe I cannot do something, it makes me incapable of doing it. But when I believe I can then I acquire the ability to do it even if I didn't have in the beginning."

2)  Do continuous effort

IIT-JEE preparation requires continuous effort. Each subject must be given proper and regular time. Instead of preparing one subject for some days then other subjects, all the three subjects (Physics, Chemistry and (Mathematics) must be given time each day. It also helps in breaking monotony.

3)  Have proper guidance

In today's competitive era, proper guidance is needed for success. The pattern of JEE has become concept based completely. So you need clear and doubtless concepts in each and every topic, to achieve a good rank in JEE.

4)  Prepare Good Notes

Prepare good notes during attending lectures or self study. If you want to make the concept more clear while preparing notes of lectures leave some space and just after lecture fill up the space with clarification.

5)  Do regular revision

Apportion proper time for each subject. The approach should be balanced. After systematically understanding the concepts practice relevant problems to consolidate the topic.

6)  Check yourself regularly

Do complete your studies by the end of January (All the three papers should be completed by the end of January or at most by the mid February), and try to give as many tests as you can. Joining test series program is not a bad idea. After each test evaluate yourself. Try to find out your weak areas, and then do research on those weak areas. Believe me; this will help you a lot.

               IIT - JEE starting preparations

       
The best time to start preparation is at the beginning of 11th class. Students are fresh after the break after boards and a lot more can be learnt. Students who start late often end up leaving some key topics of 11th class JEE syllabus. Also, if you start your preparation in 12th class then the amount of hard work is increased manifold due to additional pressure of 12th boards, so chances of getting a high rank in JEE are decreased. There is a big transition from the mugging up study of 10th class to more understanding based study of 11th class. So you shouldn't get bogged down by seeing the level of complexity in JEE exam.

The first two or three months should be spent in revising your basic concepts (topics like algebra, mechanics) which had been taught in 9th class. Concepts in topics like algebra, mechanics and stoichiometry should be studied in great detail as they also form the basis for other topics and are very scoring. There should be no doubt in your mind about these concepts. For these, develop the habit of inquisition. Clear all your doubts so that mentally you feel confident tackling any concept. A key in this area is problem-solving. Regular problem solving not only strengthens the concepts, but also increases your mental sharpness which is must for JEE. Initially problems of low level should be tried and only when you have mastered them, you should go on to solving intricate JEE type problems. You should have systematic plan for the preparation of JEE. Regular hours should be allotted to mastering concepts and problem-solving. It is not necessary to memorise the lessons and formulae. Understand the derivations of formulae and apply the formulae to solving problems. Slowly these formulae will settle down in your brain and you will be able to recall them under any situation. What is required is a clear understanding and an easy familiarity with the concepts and laws. Maximum attention should be paid to solving problems. Try to be analytical rather than being intuitive. Remember that hardwork pays! You should first take up a problem and try to solve it yourself. You should understand what is given and what is required, recall what principles, laws, equations are involved. Don't hurry to see the solution as I doesn't help you to learn. Only when you've pondered over it over a long time and unable to see any light, should you see the solutions. You would be insulting yourself and seriously hurting your chances of success if you skip these problems or make half-hearted attempts in solving them. An other very important aspect of your JEE preparation will be the coaching institute, whose importance and selection procedure will be delved into in the next section.

The application of talent at the test level is a skill that can be developed only by serious training. So it is advised that students start their specific preparation for IIT-JEE immediately after Class X.

BOOKS FOR IIT-JEE Preparation


Following are the recommended books for the Preparation of IIT JEE Examination: But I would advise that don't start solving all the books at a time, this will do nothing but waste your time. Take one as a text book, solve its problems and if you have any difficulty in solving and understanding then only refer to other books. It is strongly recommended that don't go through all the books at a time.


I would suggest the following books for IIT JEE preparation.

1. Physics:


Text Books: For solving problems and understanding basics 


  • Concept of Physics Volume 1 & Volume 2, By H C Verma

ANALYSIS OF IIT-JEE


The complexity of the IIT-JEE arises from the fact that the questions are always unique in their context, and solving them often requires a combination of concepts from across different chapters. Nonetheless, some basic data analysis can be quite revealing and could give some important insights into how one should go about preparing for each subject. Such analyses form the basis of our understanding of the JEE. The section-wise breakup of marks in the past four years (2001-2004) JEE Screening has been given below for your reference.




PHYSICS


'Electrostatics and Current Electricity', and 'Electromagnetism'-each of these topics has contributed about 15% to the total marks in the past four years. Students should devote about 30% of their preparation time to the coverage of Electromagnetism and Electrostatics; because together they constitute almost one-third of the total marks and can be more scoring as the degree of difficulty when compared to Mechanics is relatively low.

'Optics' too contributes approximately 13% to the IIT-JEE Screening test. Though this trend does not conform strongly to the 1999 JEE (which only had one test- JEE Screening was introduced in 2000). Within Optics, it has been observed that problems on Physical optics are more frequent than that on Geometrical optics. Students should take care to devote about 10% of time on Optics for robust preparation.

In the past four years, approximately 20% of the total marks pertain to Mechanics. Within Mechanics, the favorite topics seem to be 'Rigid Body Rotation' and 'Motion on a Plane'. Topics like 'Simple Harmonic Motion' and 'Work and Energy', on the other hand, have been accorded relatively less priority for these years. Apparently, students have to be thoroughly prepared with Mechanics as it forms almost one-fifth of the whole JEE Screening paper. It is important for students to realize that Mechanics though important, takes relatively more time for preparation. Thus, they should restrict their preparation of Mechanics to about 30% of the total time. The next important topics are 'Modern Physics' and 'Thermal Physics', each commanding a share of about 12% of the total marks. These topics can be covered thoroughly in a relatively less time (10% of total time can be allocated to each topic); therefore, a student should look at exhaustively preparing for these topics.

The last but not the least, 'Mechanical Waves' (sound) has accounted for approximately 12% of the total marks. Students can prepare for Wave Motion by restricting their total time spent on this particular topic to about 10%.  



CHEMISTRY


'Organic Chemistry' has the highest weightage with mean marks of 36%. Topics like 'Isomerism' and 'Name Reactions', and 'Stability of reaction intermediates' should be thoroughly covered. It is easier to remember the reactions and conversions involving aromatic compounds and a considerable percentage of questions from organic chemistry are based on this part. An understanding of directive influence of substituent groups, resonance and mechanism of reactions definitely helps in cracking the problems of organic chemistry.

'Physical Chemistry' is a close second with a mean weightage of 33%. In fact, questions on physical chemistry are all numerical in nature. Problems on topics like 'Electrochemical', 'Kinetics', and 'Chemical and Ionic Equilibrium' are always asked either directly or along with some other topic. Students are advised to cover all the topics of physical chemistry. This is an area in which students can be sure of hundred percent score, provided they have a clear understanding of the concepts and a good practice of solving problems within recommended time.

'Inorganic Chemistry' and 'General Chemistry' account for 21% and 10% of the total marks. Inorganic Chemistry should be prepared by studying the group properties and periodicity. Lots of emphasis has to be given to Exceptions. Questions are asked from these topics invariably. The properties of some important compounds are also asked in the form of reactions. Remembering the reactions involved in qualitative analysis is of great advantage. Questions asked in General Chemistry mostly include that from 'Psychometric' and 'Chemical Bonding'.



MATHEMATICS


'Calculus' accounts for about 30% of the total marks in JEE Screening. Students can score a high percentage of marks by firmly grasping the fundamentals of Calculus. More emphasis should be given in preparing 'Functions', 'Increasing/Decreasing Functions', and 'Maxima/ Minima of Functions'.

In Integral Calculus, students must practice problems on 'Definite Integral' with a proper understanding of the use of their properties for evaluation.

In 'Area of Regions Bounded by Curves', students should take care to draw figures for obtaining the limits of the integrals to be evaluated.

'Algebra' has a weightage of about 23% of the total marks. Students should emphasize practicing only those topics that have been well understood by them. Since problems on Algebra are trickier, students must practice solving as many different types of problems as they can.

'Analytical Geometry' has a weightage of about 20% of the total marks. It is also a conceptual topic. Before solving a problem, students must draw figures of the given curves to understand the problem.

The topics of 'Vectors and 3-D Geometry' and 'Probability' have a weightage of approximately 6% each. These also have to be thoroughly prepared.

'Trigonometry' carries a weightage of about 9%. It has been observed that this weightage was as high as 17% in JEE Screening 2001 and as low as 4% in JEE Screening 2003. Students, anyways, must be thorough with the topics of 'Inverse functions', 'Solutions of Trigonometric Equations', and 'Solution of Triangles'. The formulae and standard results of trigonometry must be learnt by heart in order to do well in the Mathematics paper.

Please note that the JEE is not about scoring 100% in a subject or the examination. Your aim should be to attain an optimal score in each subject, depending on your strengths and weaknesses.  Remember there is an individual cutoff of each of the three papers, so you must concentrate on all the three papers.
