A forensic, question-by-question analysis of our 5 predicted practice papers against the official CBSE Class 12 Chemistry Board Exam 2026 (Code 56/1/2).
On 28 February 2026, millions of students across India sat for the CBSE Class 12 Chemistry Board Examination. In the days before the exam, Paper Predict published 5 comprehensive predicted practice papers — built through deep syllabus pattern analysis, chapter-wise weightage mapping, and historical trend modelling.
Today, we publish a transparent, question-by-question verification of how those predictions performed against the official exam paper (Code 56/1/2). The numbers speak for themselves.
Every question from the official paper was extracted and cross-referenced against all 165 questions across our 5 predicted sets:
The predicted paper contains a question with identical or near-identical wording, same concept, same format. A student who practised it would recognise the board question immediately.
The predicted paper tests the same core chemical principle using a different compound, value, or format. A student who understood it would have the tools to solve the board question.
A question is tagged No Match only when neither the format nor concept appears anywhere across all 5 sets.
| Section | Qs | Exact | Concept | None | Cover |
|---|---|---|---|---|---|
| A — MCQs | 16 | 1 | 11 | 4 | 75% |
| B — VSA | 5 | 3 | 2 | 0 | 100% |
| C — Short | 7 | 4 | 3 | 0 | 100% |
| D — Case | 2 | 2 | 0 | 0 | 100% |
| E — Long | 3 | 1 | 2 | 0 | 100% |
Sections B through E — carrying 54 of 70 marks (77%) — achieved 100% predictive coverage.
Questions where our papers had virtually the same question, format, and answer pathway:
4 questions — just 4 marks out of 70 — not found in any form:
All 4 were 1-mark MCQs. Total missed: 5.7% of the paper. Coverage: 94.3% of marks.
| Category | Qs | Marks | % |
|---|---|---|---|
| ● Exact Match | 11 | 32 | 45.7% |
| ● Concept Match | 18 | 34 | 48.6% |
| ● No Match | 4 | 4 | 5.7% |
| Total Coverage | 29 | 66/70 | 94.3% |
Exact matches alone carried 32 marks — nearly half the paper. These could be scored directly from practising our predicted papers.
Complete question-by-question analysis with match notes for all 33 questions.
| Set | Exact | Concept | Total | Strongest Topics |
|---|---|---|---|---|
| Set 1 | 3 | 7 | 10 | Coordination, electrochemistry, sugars |
| Set 2 | 4 | 5 | 9 | Raoult's law, rate expressions, organic ID |
| Set 3 | 5 | 5 | 10 | Kinetics, haloarenes, azeotropes, VBT/CFT |
| Set 4 | 3 | 8 | 11 | Named reactions, amines, TM properties |
| Set 5 | 2 | 10 | 12 | Colligative properties, CFT, biomolecules |
Set 3 had the most exact matches (5). Set 5 had broadest reach (12). The 5-paper strategy delivered comprehensive coverage no single paper could.
When predicted papers cover 94.3% of marks before the exam, that's an extraordinary strategic advantage. Paper Predict combines deep historical analysis of CBSE patterns spanning a decade, chapter-wise weightage mapping, and systematic identification of recurring templates.
This is exam prediction as a science, not a gamble.
All 5 predicted practice papers that achieved 87.8% accuracy were shared on our Telegram channel before the examination.
