CBSE News July 25, 2026: Class 12 Supplementary Exam July 28, NEP Training, Study Resources & Top Subject Q&As

Three days remain until the CBSE Class 12 Supplementary Examination 2026, scheduled for Tuesday, 28 July 2026. This week is also the start of CBSE's national NEP 2020 Training Programme for educators (July 27–31), while the Class 10 Compartment Result is expected in the first week of August. This post covers every critical CBSE development this week — from final exam-day preparation and subject tips to 2026-27 curriculum updates, popular board exam questions with model answers, and a complete list of free official study resources.

1. CBSE Class 12 Supplementary Examination — July 28, 2026

The CBSE Senior Secondary Supplementary Examination 2026 is scheduled for 28 July 2026 (Tuesday). All subjects are conducted on the same day.

Exam Timing

Who Should Appear?

• Students placed in Compartment after the CBSE Class 12 Board Exam 2026 (up to 2 subjects)
• Students from the 2025 batch still in compartment — this is the third and final attempt
• Students who passed but want to improve their score in one subject

Final Day Preparation Checklist

• Download your admit card from cbse.gov.in immediately — entry is not permitted without it
• Mathematics: Prioritise Integrals, Differential Equations, Matrices, and Probability (highest weightage units)
• Physics: Revise derivations (Gauss's Law, Biot-Savart, lens formula) and solve numericals from Electrostatics and Optics
• Chemistry: Focus on named reactions (Organic), electrode potentials (Electrochemistry), and mole concept calculations
• Biology: Draw and label diagrams — nephron, meiosis stages, DNA replication — each can earn 3–5 marks independently
• English: Practise unseen passage structure (skim → identify theme → answer specifically), letter format, and prescribed novel character analysis
• Economics: Revise definitions, difference comparison tables (Micro vs Macro), and diagram-based 3–4 mark questions
• Get 8 hours of sleep the night before — fatigue causes avoidable calculation errors

Practical Examinations

CBSE has scheduled Supplementary Practical Exams from 29 July to 4 August 2026. Students must contact their school or examination centre with a copy of their result and admit card by 27 July 2026 (tomorrow).

2. CBSE Class 10 — Compartment Exam & Result Update

Class 10 Compartment Exam 2026

Students who are still in Compartment after the Class 10 Phase 2 Result (declared July 18, 2026) are eligible for the Class 10 Compartment Exam.

• Compartment Exam: Expected in August 2026 — exact dates awaited from CBSE
• Compartment Result: Expected in the first week of August 2026
• How to check: cbseresults.nic.in using Roll Number, School Number, Admit Card ID, and Date of Birth

What to Do If You Are in Compartment

1. Contact your school today to confirm your name is on the LOC (List of Candidates) for the compartment exam

2. Begin focused NCERT revision from Day 1 — even 2–3 hours daily for 10 days is sufficient to clear a single subject

3. Focus on CBSE sample papers and previous year papers for the specific subject you need to clear

3. NEP 2020 Training Programme — July 27–31, 2026

CBSE has announced an Online Training Programme titled "NEP 2020: Empowering SEDGs" running from 27 to 31 July 2026.

What Are SEDGs?

SEDGs (Socially and Economically Disadvantaged Groups) include children with disabilities, children from SC/ST/OBC communities, first-generation learners, girls in rural areas, and children in conflict-affected zones. NEP 2020 places specific emphasis on ensuring these students are not left behind as education becomes more digital and competency-focused.

Training Modules

For Teachers: This training is recommended for all CBSE school educators and will be reflected in professional development records. Registration is through your school principal on the CBSE Training Portal at cbseit.in.

4. CBSE 2026-27 Curriculum — What Students Starting New Classes Must Know

If you are entering Class 9, 10, 11, or 12 in July–August 2026, the curriculum has changed in important ways this year.

Key Changes for Classes 9 & 10

Key Changes for Classes 11 & 12

5. Popular CBSE Board Exam Questions — Model Answers

Class 10 Mathematics

Q1: State and prove the Basic Proportionality Theorem (BPT).

Statement: If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

Proof (steps required for full marks):

• Draw triangle ABC with DE ∥ BC, where D is on AB and E is on AC
• Draw DM ⊥ AE and EN ⊥ AD
• Area(ADE) / Area(BDE) = AD / DB (triangles with same height DM)
• Area(ADE) / Area(CED) = AE / EC (triangles with same height EN)
• Area(BDE) = Area(CED) (same base DE, between parallel lines DE and BC)
• Therefore: AD / DB = AE / EC — proved ✓

*Examiner tip: Write "Given, To Prove, Construction, Proof" as four separate headers. Never skip the construction step — it costs marks.*

Q2: Find the roots of 2x² – 7x + 3 = 0 using the quadratic formula.

a = 2, b = –7, c = 3

x = [–b ± √(b² – 4ac)] / 2a = [7 ± √(49 – 24)] / 4 = [7 ± 5] / 4

x = 3 or x = 1/2

*Verify: 2(9) – 7(3) + 3 = 0 ✓ and 2(1/4) – 7(1/2) + 3 = 1/2 – 7/2 + 3 = 0 ✓*

Q3: In an AP the first term is 5 and common difference is 3. Find the 20th term and sum of the first 20 terms.

a = 5, d = 3

20th term: a₂₀ = a + 19d = 5 + 57 = 62

Sum of 20 terms: S₂₀ = 20/2 × [2(5) + 19(3)] = 10 × 67 = 670

Class 10 Science

Q4: Describe the structure and function of a nephron with a labelled diagram.

A nephron is the structural and functional unit of the kidney. Each kidney contains approximately one million nephrons.

Key structures for diagram (label all four for full marks):

• Bowman's Capsule — cup-shaped; encloses the glomerulus; site of ultrafiltration
• Glomerulus — network of capillaries under high pressure; blood is filtered here
• Proximal Convoluted Tubule (PCT) — reabsorbs glucose, amino acids, and most water
• Loop of Henle — concentrates filtrate; descending limb is water-permeable, ascending limb is not
• Distal Convoluted Tubule (DCT) — selective reabsorption; regulated by ADH and aldosterone
• Collecting Duct — collects urine; further water reabsorption before draining to the ureter

Process summary: High-pressure blood → glomerular filtration → tubular reabsorption of useful substances → tubular secretion of waste → concentrated urine exits via ureter

*5-mark answers require a neat diagram with at least 4 labelled parts plus a process description.*

Q5: Compare aerobic and anaerobic respiration.

Class 12 Mathematics

Q6: Evaluate ∫ x · eˣ dx using integration by parts.

Using ∫ u dv = uv – ∫ v du (ILATE rule: Algebraic before Exponential → u = x)

Let u = x, dv = eˣ dx → du = dx, v = eˣ

∫ x · eˣ dx = x · eˣ – ∫ eˣ dx = eˣ(x – 1) + C

Q7: Find the area bounded by y = x² and y = x.

Step 1 — Intersection points: x² = x → x = 0 and x = 1

Step 2 — Which curve is on top in [0, 1]? At x = 0.5: y = x gives 0.5, y = x² gives 0.25. So y = x is above y = x².

Step 3 — Area:

Area = ∫₀¹ (x – x²) dx = [x²/2 – x³/3]₀¹ = 1/2 – 1/3 = 1/6 square units

Class 12 Physics

Q8: State Gauss's Law and derive the electric field due to an infinite plane sheet of charge.

Gauss's Law: The total electric flux through any closed surface equals the net charge enclosed divided by ε₀:

∮ E · dA = Q_enc / ε₀

Derivation for infinite plane sheet (surface charge density σ):

• Choose a cylindrical Gaussian surface of cross-section area A passing symmetrically through the sheet
• By symmetry, E is perpendicular to the sheet and parallel to the curved surface → flux through curved part = 0
• Total flux = E·A + E·A = 2EA (two flat faces)
• Charge enclosed = σA
• By Gauss's Law: 2EA = σA / ε₀
• Therefore E = σ / (2ε₀), directed away from the sheet for positive σ

8. Top Student FAQs — July 25, 2026

Q9: Is the July 28 Supplementary Exam the last chance to pass Class 12?

For students from the 2026 batch: yes, this is the only supplementary sitting. If you do not clear it, you must appear as a private candidate in the 2027 CBSE Board Exam. For 2025 batch students still in compartment: this is the third and final compartment attempt — after this, re-registration as a fresh candidate is required.

Q10: Can I improve my CBSE Class 12 score even if I already passed?

Yes. Passed students from the 2026 batch can appear in the supplementary exam to improve their score in one subject. The higher of the two marks (original board and supplementary) is taken as the final score. This is especially useful for students who narrowly missed the percentage threshold for a specific college course.

Q11: What is APAAR ID and is it mandatory for CBSE students?

APAAR (Automated Permanent Academic Account Registry) is India's national student ID system under the One Nation One Student ID initiative. It links your academic records to DigiLocker. From 2026-27, CBSE has made APAAR ID registration mandatory for all enrolled students. Your school is responsible for generating and linking your APAAR ID — if not done yet, contact your class teacher or principal immediately.

Q12: What is the open-book exam pilot and does it affect board exams?

CBSE is piloting Open Book Examinations (OBE) for Class 9 and 11 in selected schools during 2026-27. In OBE, students may bring NCERT textbooks and notes into the exam — but questions test application, analysis, and synthesis, not memorisation. This pilot does not affect the standard Class 10 or Class 12 board exams in the near future. Students should not change their study approach based on the OBE pilot unless their school is specifically part of it.

Q13: How many languages must a student study under the new CBSE curriculum?

Under the three-language formula (mandatory from Class 6 in 2026-27):

• Three languages in total, of which at least two must be Indian languages
• Two languages are compulsory board exam subjects in Classes 9–10; the third continues as an elective
• Common combinations: Hindi + English + Sanskrit, Hindi + English + French, Hindi + English + Regional Language

Q14: Is NCERT enough to score 90%+ in CBSE board exams?

Yes — NCERT textbooks are the primary and sufficient source for CBSE board exams. Board questions are drawn directly or indirectly from NCERT content. To score 90%+: (1) complete every NCERT exercise and example problem; (2) practise official CBSE sample papers to understand how questions are framed; (3) solve at least 5 previous board papers under timed conditions. Reference books by private publishers add value for competitive exam preparation but are not necessary for 90%+ in boards.

Summary

The week of July 25–31, 2026 is among the busiest in the CBSE calendar. Students appearing for the Class 12 Supplementary Exam on July 28 must download their admit card today, complete final revision tonight, and rest well. Those waiting on the Class 10 Compartment Result can expect it in early August. Educators should register for the NEP 2020 SEDG Training starting July 27. Students entering the new 2026-27 academic year face a changed curriculum — three languages, two-level Maths and Science, and a heavily competency-based exam pattern. Starting with updated NCERT books and building a consistent daily study habit from Week 1 is the single most effective preparation strategy.
