The Joint entrance test (Jee) conducted by the Indian Institutes of Technology (Iits) is one of the most competing exams in India, with nearly 3.5 lakh aspirants appearing for it. However, only about 5,000 students are selected. Here are a few tips to help you make the cut if you're planning on appearing for the Jee in 2009/2010.
Format Of The Exam
The format of Jee papers keeps changing. However, for the last three years, the format has included two detach papers of three hours each. Both these papers contain three sections on physics, chemistry and mathematics. The questions in these papers are of the senior-secondary academic level imaginable at the stage. Each section includes questions under different headings.
Master Mathematics
To score in mathematics, you need to have the capability to solve simple, stereotypical questions, as well as inspiring and complicated problems that you might have to face unexpectedly.
Before you solve a problem, you must:
(a) Identify exactly what needs to be answered
(b) Identify the data and conditions that will guide you to the answer
(c) Visualise the problem mentally and, if needed, draw a sketch or diagram from the given data and write the thorough symbols and equations
1. While attempting questions, try not make make any singular problem a credit issue. Hence, if you are unable to solve the problem within a cheap number of time, you should skip the ask and move on. All the time remember that There may be simpler problems awaiting you
2. Don't be tempted to guess the acknowledge to a question. It may prove costly if there is negative marking
3. Also, All the time try and attempt some mock ask papers in a simulated environment before the D-day. In fact, there are many online tests that contribute useful mock convention tests for students. One such website is
Step-wise problem solving skills
1. Read and understand the problem clearly - (a) What am I supposed to find? (b) What am I solving for? (c) What data and conditions have been provided?
2. Develop and carry out a plan of activity - (a) Have I ever solved a similar problem? (b) What strategy should be followed? (c) How do I apply the skills needed to implement a strategy?
3. Find the acknowledge and check it - (a) Does the proposed clarification seem to be reasonable? (b) Does the proposed clarification need to be checked? In many option questions or multiple-answer questions, try to identify the choices that cannot be strict or choices that immediately follow from the other choices
For Physics
The format of the physics section in the Jee ask paper changes every year. Subjective problems, which involve detailed solutions, have been dispensed with. For the first time, in Jee-2007, questions based on paragraph, assertion-reason type questions and questions on matrix matching were included. In Jee-2008, Mcqs with more than one strict option were included in the paper.
Studying tips
1. Learn the definitions and formulae in each episode first. It is important to understand the assumptions complicated in deriving a formula. The technique and mathematical tools and logic used must be clearly recognised and understood
2. Write down leading formulae in a detach notebook. Also, make a note of extra techniques used in solving some problems in the chapter. These notes should be made for all the chapters. They will be useful before the exam, when you have wee time
3. Carefully tell chapters and recall the formulae, laws and techniques in the chapters. If you are unable to recall them, refer to your notes
Identification of problem areas
In each chapter, identify the problem areas, which need closer study. get ready a note of the questions you failed to solve in the first attempt. Write down the strict solutions in a detach notebook. If you are unable to solve a problem, consult your teacher. In physics, checking the given option for dimensional consistency is often very helpful.
Questions based on experiments
In the physics paper, there is at least one ask based on an experiment. You must learn how to resolve the least count of measuring instruments such as vernier calipers, micrometer screw and spherometer, and to use them in production measurements. The rules of determining the important figures in the follow of a calculation must be clearly understood.
Books recommended for physics
1. Fundamentals of Physics by Halliday, Resnick and Walker 2. Developed Level Physics by Nelkon and Parker 3. Physics of class Xi and Xii by Ncert
Chemistry
The three branches of chemistry are evenly represented in both the papers in the Jee. The chemistry paper in the year 2008 was in the following format in both Paper I and Paper Ii: Straight-objective type: This involves questions with four alternative answers, of which only one is correct. Multiple-correct acknowledge type: This involves questions with four alternative answers, of which more than one is correct. Thinking type: Here, each ask involves two statements, which have to be correlated with each other. Only one acknowledge is correct. Linked-comprehension type: This is a paragraph stating obvious facts, from which a set of three questions is framed with four alternative answers, of which only one is correct.
Physical chemistry
The branch matter in physical chemistry involves topics with well-focused principles. Their application to different problems is straightforward. You should pay more attentiveness to this branch of chemistry so that you can solve problems associated to it more comfortably. Be fully ready with: Bohr's principles of atomic structure, quantum numbers and orbitals Mo coming to diatomic molecules, hybridisation/ Vsepr principles Vander Waals equation of state and application to behaviour of real gases Crystal systems, packing of atoms, ionic solids and density of crystals Colligative properties of non-electrolytic and electrolytic solutions Electrolysis, conductance and electric cells Differential and integrated rate laws, follow of catalyst and climatic characteristic on the rate of reaction estimation of Ph of acids, bases and salt solutions (including hydrolysis) and solubility product Le-Chatelier Principle, relation between Kp and Kc Stability of nuclei Thermo-chemical calculations and criterion of spontaneity
As for inorganic and organic chemistry, be ready with:
Inorganic chemistry
Boron and its compounds Silicates and silicones Oxoacids of phosphorus, sulphur and halogens Inter halogens and compounds of noble gases leading compounds such as H2O2, Nahco3, Na2Co3, KmnO4, K2Cr2O7 Transition elements, lanthanides and coordination compounds Quantitative prognosis of salts
Organic chemistry
Isomerism, with optic isomerism Inductive and resonance effects on acidity and basicity of acids and bases Factors affecting Sn1/Sn2 reactions Reactions inspiring rearrangement Bromination and hydrogenerations of cis-and-transalkenes; debromination of different isomers of 2, 3-dibromobutane Reimer-Tiemann reaction Characteristic reactions of ketorres, aldehydes and carboxylic-acid derivatives Reactions with Grignar reagent and those of diazonium salt Carbohydrates and polymers Qualitative prognosis of organic compounds
