NCERT vs Reference Books: Which is Enough to Crack JEE 2027

If you are a JEE Aspirant and you’re sitting at your desk, a mountain of heavy, expensive reference books on one side and a slim, slightly worn-out NCERT on the other. Many teachers have different opinions on this topic; some say NCERT is enough, while others promote their own written books. In 2026, when the competition is peaking and the exam pattern is moving towards conceptual depth, is NCERT really enough? The Short answer is No, but also Yes.

Chemistry in JEE (Rank Booster)

Before 2026, chemistry was one of the easiest and most scoring subjects in JEE, but after the pattern change in 2026, JEE is asking more statement questions. If there is one subject where NCERT is the king is Chemistry. Let’s talk about the parts of chemistry:

Inorganic Chemistry: It is one of the most scoring parts among all three because we don’t want to solve numerical problems like those in physical chemistry or complex reactions in organic chemistry. NTA loves picking lines from the middle of the NCERT paragraph in the p-block or d-block and turning them into statement-based questions. NCERT is enough for inorganic chemistry. If you have time, then solve PYQs of the last 10 years, which is more than enough for your JEE exam.

Organic Chemistry: NCERT helps to build logic, but we need a reference to understand the why behind the mechanism. The Best reference book that most of the toppers use is M.S. Chauhan. I see many students start M.S. Chauhan, but quit within two weeks because it’s too hard. These are the points you must know before solving M.S. Chauhan.

• Don’t touch it without theory – First, read the NCERT or your coaching modules before starting M.S. Chauhan.
• First, solve level 1, because if you direct jump to level 2, it will frustrate you.
• The Solution Trap: If you get stuck, don’t look at the solution immediately. Staring at a mechanism for 10 minutes and failing is better for your brain than looking at the answer in 10 seconds.
• Selective Solving: You don’t have to solve all 500 questions in one go. Pick 30-40 diverse problems per chapter. Quality > Quantity.

Physical Chemistry: First, use the NCERT to learn the formulas and theory, and then you need a reference book to practice the maths. You can buy Narendra Awasthi (N. Awasthi) sir’s book for practising the different levels of questions. Tip – Don’t try to solve every single question. Do the “odd” numbers first. If you get them right, move to the next level.

Physics in JEE (Concept vs. The Calculation)

Physics is where most students fall into the NCERT Trap. NCERT Physics is brilliant for understanding theory and derivations (essential for Boards). However, JEE is about application. For example, NCERT will teach you the formula for the Electric Field:

But a JEE question will ask you to calculate the field at the centre of a non-uniformly charged semi-circular ring. NCERT won’t prepare you for that; H.C. Verma or Cengage will.

If you are a serious aspirant and want a top rank in 2027, you will likely have both of these on your shelf, but knowing when to open which book is the secret to not wasting time.

Mathematics: Practice is Everything

If you are solving the NCERT in Mathematics, then you are wasting time because the NCERT Mathematics is level 0 for JEE. It’s great for clearing your Class 12 Boards with 95%+, but for JEE? It’s just the warm-up. You can use BlackBook to solve the problem, but in mathematics, your coaching modules are the key. In mathematics, no theory can give you marks; only practising complex questions can make your mind a JEE-level thinker.
