An IITian Tells You if NCERT is Enough For JEE (Mains)

JEE (Mains) is based on the concepts given in NCERT textbooks. The answer to the above question is, however, equivocal. It relies on the relative aspirations of the students.
I have the experience of solving the AIEEE Papers from 2008-2012 and I have appeared in JEE (Mains) 2013 and 2014. From my experience, I can say that” If you are thorough with NCERT, then you can score easily around 200/360. But it is definitely not enough to score above 250.” A genuine doubt which may arise is that if one can score above 200 with simply covering the NCERT, why is then only less than 15,000 students out of 14 lakh students appearing in the exam achieve that feat.

I have two plausible explanations to this. First, NCERT text books are full of jargons and it requires a lot of depth to assimilate them. There are certain concepts in NCERT which are not explicitly specified. Students have to derive meanings on their own. To elucidate my point I would like to quote an example. NCERT Chemistry textbook merely states the Markownikoff Rule and Saytzeff Rule without giving an insight into the reaction intermediate formed, that governs the formation of the final product. A student who simply follows the NCERT will end up mugging up the lines, without actually understanding the mechanisms. Second, NCERT textbooks lack enough practice questions. Being thorough with the concepts demands rigorous practice and regular brush-up of your concepts. Students who are not exposed to any practice materials like question banks but NCERT are used to a straight-forward way of answering subjective questions. But Multiple Choice Questions (MCQs) are asked in JEE (Mains), which are often confounding. Definitely, NCERT is not enough.
However, if you analyze the questions asked in previous years, you will find at least one direct organic reaction is asked from the NCERT. Even the questions of p-block and other inorganic reactions asked in the exam are never beyond NCERT and are usually straight-forward. Physical chemistry, however, demands problem-solving aptitude which requires you to go beyond NCERT. There are some topics like Statistics, Mathematical Reasoning in Mathematics, from which at least one question is asked every year and these are directly based on NCERT. Even the questions from 3D Geometry, vectors, complex numbers and coordinate geometry are based on NCERT exercise questions. Physics, however, requires a different approach. One has to solve problems from books like H.C. Verma, in addition to the NCERT questions to gain a good command over the subject. Nevertheless, the questions asked in electromagnetism, fluid mechanics and even modern physics are often directly taken from NCERT. ‘Semi-conductor devices’, ‘Electromagnetic Waves’ and ‘Communication’ are the topics which are factual. But the facts and figures, if ever asked, are never beyond NCERT.
One of the best ways to excel in any exam is to solve the previous years’ papers. This will give an insight into the types of questions being asked in the exam. Once you start solving these questions, a feeling will sink into you that many questions are NCERT based. Develop an ability to question mere statements of NCERT. I hope my article proves helpful for the students and instil a belief that they can clear JEE (Mains) with a good rank by having a thorough understanding of the concepts of NCERT.

Inorganic Chemistry Plan for JEE Advanced


It is always a hazy area on what to cover in Inorganic chemistry for JEE
Advanced for good number of students. 

Should we just do inorganic NCERT?

or cover reference books too? 





which question banks to cover? and so on...

Based on my experience of JEE Advanced paper trends, this is what I
would like to share with all the serious aspirants for JEE Advanced.

Inorganic in JEE advanced is strictly on the NCERT reactions and
questions are related to the content given In the NCERT. The following
points must be understood to know how to prepare for inorganic for
advanced.

    * All the chemical reactions given in NCERT must be learnt or
understood. In advance the 2–3 reaction based questioned are asked e.g
. A road map type question, identification of compounds based on
characteristics given, possible reactions, and properties exhibited by
compounds etc. These questions are strictly based on the reactions given
in the NCERT.
    * In JEE advance there are questions describing or asking the molecular
characteristics such as bond angle, bond length, shape, order of
solubility, stability, melting boiling points, planarity, polarity,
colour, solubility in conc HNO3, NH3, KCN, NaOH etc, of different
compounds. Such questions often inquire the above mentioned
characteristics for compounds given in NCERT but not always. because the
JEE don't expect you to cram all these but instead deduce using
theoretical concepts or correlation.
    * The JEE have been asking at least one question strictly outside the
NCERT but 90% of them can be solved but only by potential AIR 1
candidate (extremely intelligent) or a very well learned intellectual
inorganic faculty. Though there are 10% chances that even the above
mentioned faculties might need to refer some university level inorganic
books (reference books)
