Preparation Strategy for IIT- JEE (Main)
JEE (Main) syllabus
The syllabus of JEE main is the syllabus followed by CBSE board. In fact, the JEE Main syllabus can be considered a replica of what was covered in previously held AIEEE exam. All the topics of JEE Main are covered in NCERT books.
Different sections in exam
Since the JEE main is being conducted by the CBSE, the same body that was conducting the AIEEE earlier, it is expected that the similar pattern shall continue in JEE Main as well. In AIEEE, the paper was not divided into sections. But the questions that were asked in the AIEEE were of three types
Straight objective type multiple choice questions
Linked comprehension type questions
Assertion-Reason type questions
Generally there are 5 Assertion-Reason Type questions, and 25 multiple choice questions including the linked comprehension type questions.
General preparation strategy
The JEE Main paper is a race against time. It is important to optimise your performance by practicing a good number of MCQs. There are 90 questions in all to be done in 3 hours duration.
Most important topics
Physics: understanding of Kinematics and Dynamics is very essential to be able to build a strong problem solving ability. Also, the Theory of Fields (Electromagnetism) is very important and a large number of problems are asked from it.
Chemistry: Physical Chemistry is very scoring and all the units in it must be done carefully. Students tend to neglect Inorganic Chemistry but if studied in a proper way, it becomes very scoring.
Mathematics: Calculus is very important to learn as it finds applications in all domains. Other important and scoring topics are Determinants, Sequences, Permutation and Combination. The student must be able to relate the complex numbers with Coordinate Geometry and Vectors. Three dimensional geometry is easy and scoring if done properly.
