CBSE Class 12 Science: 3-Year Weightage & Trend Analysis (2024-2026)

 

CBSE Class 12 Science: 3-Year Weightage & Trend Analysis (2024-2026)

A Detailed Comparison of Physics, Chemistry, Biology & Maths Marking Schemes

Over the last three years, CBSE has moved away from rote memorization. In 2024, direct questions and derivations dominated. By 2026, "Competency-Based Questions" (Case Studies and MCQs) have increased to 50% of the total weightage. This means students must now focus on application rather than just definitions.

2. Physics (Theory - 70 Marks): 3-Year Mark Distribution

Unit Name 2024 2025 2026 (Exp.)
Optics (Ray & Wave)181818
Electrostatics + Current Electricity161616
Magnetic Effects & AC/EMI171717
Electronic Devices (Semiconductors)070707
Modern Physics (Dual Nature/Atoms)121212

3. Chemistry (Theory - 70 Marks): The Rise of Organic

In Chemistry, the weightage of Organic Chemistry has remained rock-solid at 26-28 marks. However, the complexity of Bio-molecules has seen a subtle increase in weightage due to its relevance in NEET.

Subject Pillar 2024 Marks 2026 Marks
Physical Chemistry (Solutions, Kinetics, Electro)2323
Inorganic Chemistry (d, f, Coordination)1414
Organic Chemistry (Entire)3333

4. Question Pattern Evolution (2024 vs 2026)

This table is crucial for your preparation strategy. It shows how the type of questions has changed:

Question Type 2024 Pattern 2026 Pattern
Competency/Case-Based 40% 50%
MCQs (Standalone) 20% 20%
Subjective (Short/Long) 40% 30%

निष्कर्ष (Conclusion):

While the total marks remain 70/80, the focus has drastically shifted toward Objective and Application-based learning. If you are preparing for JEE/NEET, this pattern is in your favor as it aligns with competitive exam styles.

Indefinite Integration: Complete Notes for JEE Mains & Advanced

Indefinite Integration – Complete Revision (JEE Mains & Advanced) Indefinite Integration is not about memorising random formulas — it is about identifying forms . JEE strictly rotates questions around a fixed set of standard integrals and methods . This note covers the entire official syllabus with zero gaps. 1. Definition \[ \int f(x)\,dx = F(x)+C \quad \text{where } \frac{dF}{dx}=f(x) \] 2. ALL Standard Integrals (Must Memorise) \(\int x^n dx = \frac{x^{n+1}}{n+1}+C,\; n\neq-1\) \(\int \frac{1}{x}dx = \ln|x|+C\) \(\int e^x dx = e^x+C\) \(\int a^x dx = \frac{a^x}{\ln a}+C\) \(\int \sin x dx = -\cos x + C\) \(\int \cos x dx = \sin x + C\) \(\int \sec^2 x dx = \tan x + C\) \(\int \csc^2 x dx = -\cot x + C\) \(\int \sec x\tan x dx = \sec x + C\) \(\int \csc x\cot x dx = -\csc x + C\) 3. SIX IMPORTANT FORMS (JEE CORE) Form 1: \(\int \frac{1}{x^2+a^2}dx\) \[ = \frac{1}{a}\tan^{-1}\frac{x}{a}+C \] Form 2: \(\int \frac{1}{\sqrt{a^2-x^2}}dx\) \[...
