Engineering Entrance Exam

The Joint Entrance Examination (JEE), comprises of multiple-choice questions that test the applicant's knowledge in several Engineering-related fields. The JEE is offered at two levels:
1. JEE Main and
2. JEE Advanced.
Like with any serious academic test, thorough preparation is key to earn a good score on the JEE.
Understand the structure of the Main exam. The JEE Main lasts three hours and consists of 90 multiple-choice questions. The exam consists of three sections: Physics, Chemistry and Mathematics. Each section contains 30 questions. All sections are weighed equally. For each question answered correctly, four points are awarded. For each incorrect answer, one point is deducted. No points are awarded or deducted for unanswered questions.
Understand the structure of the Advanced Exam. The JEE Advanced is structured differently than the Main exam. The advanced exam covers the same three topics: Physics, Chemistry, and Mathematics. However, unlike the main exam, the advanced exam is divided into two three-hour long papers, each divided into three sections (one for each topic). The papers are organized as follows: -
1. Paper One:
Each section contains 10 multiple choice questions with one correct answer, five multiple choice questions with one or more correct answers, and five questions that require the test taker to provide a single-digit answer.
2. Paper Two:
Each section contains eight multiple choice questions with one correct answer, eight questions that require responding to a reading passage, and several "matching list" type questions.
Know the topics covered by each test. Though both the JEE Main and JEE Advanced cover the same three subjects (Physics, Chemistry, and Mathematics), the precise topics covered and the difficulty of the individual questions will vary between the two tests. To gain a sense for the topics you may be expected to know for each test, consult the official test syllabus for the Main and Advanced exams, both of which are available in free PDF form from official test resources online.
Below are just a few examples of the topics you may encounter on the test, these lists are by no means complete or definitive:
1. Physics:
Kinematics, laws of motion, gravity, thermodynamics, electromagnetism, optics, electronic devices.
2. Chemistry:
States of matter, atomic structure, redox reactions, chemical kinetics, environmental chemistry, periodic groups, basic organic chemistry.

Hi Ajay,
Well, it is tough, but if you have proper guidance and some confidence during the most crucial stage of preparation, then you can sail your ship through. It all depends on how well is your IIT JEE Preparation Strategy.
Tips and tricks that will help you in preparation for IIT JEE.
1. Keep your focus right
2. Identify the correct study material
Referring the right JEE Preparation Books is as important as putting in the right amount of time for studies. Though the theories, formulae, and basic matter remain the same in each book, there are certain things that set apart one book from the rest.
3. Become a part of a healthy study group
4. Avoid over-thinking
5. Eat and sleep right
6. Know the examination structure
Your preparation will be in the correct direction only when you are well aware about the structure and pattern of the exam. Knowing this will give a clear idea of how you need to move further.
