3. What is the syllabus of IITJEE Physics
Answer:Please check following link
Physics Syllabus
4.What are the study Tips for IITJEE/AIEEE?
Answer: Please take a look at the following links.These provide some tips for the exams
Study Tips for IITJEE PART 1
Study Tips for IITJEE PART 1
5.What is the right time to start preparing for IIT-JEE?
Answer:One must start just after clearing class X'th . In such a scenario the student gets adequate time of 2 years to prepare for the IIT-JEE. This ensure that his/her preparation for the IIT-JEE is complete before the pressure of Board
examinations begins to tell. Also one should concentrate on concept.
6.How do we manage both the school syllabus and preparation for the IIT-JEE?
Answer:The syllabi of the IIT-JEE is almost the same as that of CBSE Board exams. The only difference lies in the approach. IITJEE papers requires more clarity and deep understanding of the concept while CBSE board papers give more stress on
reproducing the facts.So be regular in your classes.Try the understand the concept.Do it two three time so that you learn the concept by heart.Also proper time management will help like give atleast 2 hrs for ITTJEE.
7.Which is the easiest topics to score?
Answer:
Thermodynamics is quite simple to master .JEE paper always have few question from it.So easy to score those.
Hydrostatics and Bernoulli's Principle is also simple.
Waves in Elastic Media is simple to master.JEE always have one or two question from it.
Interference Beats and Doppler's Effect is quite simple..So this is also scoring
Electrostatics :Coloumbs law,Potential,electric question are simple to attempt.
Electromagnetic Induction
Lorentz' Forces:Simple question from it.
Circuits with Capacitors:Easier to attempt with some practice and method to solve the circuits
Modern Physics (full):Always have some question from it.Easiar to master
Collisions:JEE paper have difficult question from this but easiar then below topics.It should attempted in the last
Rotational Motion:bit tough.It should attempted in the last

Study tips for IITJEE
PART -II
1.Try to visualize the problem by drawing the diagram.Free body diagram helps in solving mechanics problem.
2.Be sure your units are correct.It will many times prevent making mistakes.
3.Whenever you get any numerical answer,Judge the answer.Does the number look practical
4.Try to Break the problems into manageable pieces
5. Read your text books no of times so that you understand concept in each line
6.Do not panic in exam if you are not able to solve first problem.stay cool and attempt the other one.Most of the times we get panic lose all the time.
7 After every mock test,check your mistakes and try to avoid them again.Try to Learn something from each test
8.IITJEE may change the pattern but concept will remain same always,so if you are good,You should not worry about the pattern
9.Enter the examination in a positive mood to crack the test.
10. Prepare all the stationeries before hand.
11. Stay relax. A calm mind works better
12. Be very careful while reading the instructions,you might know the answer,but you fill it incorrectly so you will lose even what you know.
13. It is not important to attempt many question.You aim should be do the question correct.This way you will avoid negative marks.
14.You should reach the test centre at least half an hour before the exam.So that you can relax.
15.Master Time Management Skills
16.Scan all the topics in a stipulated time frame.
17. Plan your schedule for your revision and exercise.
18 .Start concentration on the topics that you have covered rather wasting time on new topics particularly when exam is just few days ahead.
