December is the month when clarity matters more than effort. With board exams approaching, most students feel stuck between two questions:
- “Ab kya padhna chahiye?”
- “Aur kya chhod dena safe hai?”
At this stage, studying everything again is neither practical nor effective. December is not about covering more chapters; it’s about making smart academic decisions. This blog acts as a final revision guide for CBSE Class 10 and 12 students, helping them decide what to focus on, what to revise lightly, and what to skip to maximize scores.
Why December Revision Needs a Different Approach
By December:
- Syllabus is mostly completed
- Pre-boards are ongoing or about to begin
- Time is limited
- Stress levels are high
This means:
- Random revision won’t work anymore.
- Selective, exam-oriented revision will.
Students who score high in boards are not the ones who study everything again; they are the ones who revise the right things at the right time.
The Golden Rule of December Preparation
Before we break it down class-wise, remember this simple rule:
In December, 70% of your time should go into high-weightage + familiar chapters, and only 30% into weaker areas.
Trying to “fix everything” usually leads to confusion and burnout.
For CBSE Class 10 Students
What to Study Seriously in December
1. Science (High Priority)
Focus on:
- Chemistry chapters (Reactions, Acids, Metals & Non-metals, Carbon Compounds)
- Biology chapters with diagrams and definitions
- Physics numericals + laws
Why?
Science is concept-based and scoring if revised properly. NCERT lines, diagrams, and numericals must be crystal clear.
2. Mathematics
Must-do areas:
- Trigonometry (identities + applications)
- Algebra (polynomials, quadratic equations)
- Geometry basics + theorems
- Statistics & Probability
December goal:
- Accuracy
- Step-wise presentation
- Speed
3. Social Science
High-scoring areas:
- Civics (short, direct answers)
- Economics (definitions + numericals)
- History timelines
- Geography maps & diagrams
Revise using short notes + previous year questions.
4. English
Focus on:
- Writing formats (letters, articles, notices)
- Grammar rules
- Important literature questions
English marks depend heavily on presentation and practice, not mugging.
What Class 10 Students Can Skip or Minimize
- Very low-weight chapters you already understand
- Rewriting entire notes again
- Studying from multiple guidebooks
- Memorizing answers word-to-word
If you know a chapter reasonably well, don’t over-revise it.

For CBSE Class 12 Students
Class 12 syllabus is vast, and December demands strong filtering.
What to Study Seriously in December
Science Stream (PCM / PCB)
Physics
- Numericals & derivations from core chapters
- Formula clarity + unit accuracy
Chemistry
- Organic reactions & mechanisms
- Named reactions
- Inorganic NCERT lines
Biology
- Human Physiology
- Genetics & Evolution
- Ecology
- Diagrams + keywords
Focus on NCERT-based conceptual clarity, which benefits boards and NEET both.
Commerce Stream
Accountancy
- Balance sheet formats
- Adjustment entries
- Cash flow statements
Business Studies
- Case-study questions
- Definitions + headings
- Chapter summaries
Economics
- Diagrams
- Numericals
- Key terms
Presentation and structure decide marks here.
Humanities Stream
High-priority focus:
- Political Science case-based answers
- History long answers with headings
- Geography maps + diagrams
- Psychology definitions + applications
Write answers daily; Humanities marks depend heavily on expression quality.
What Class 12 Students Should Avoid in December
- Starting brand-new chapters from scratch
- Ignoring NCERT and using only reference books
- Studying theory without answer-writing practice
- Giving mocks without analysing them
December is about revision + refinement, not expansion.
The “Must Do – Good to Do – Can Skip” Formula
Use this for every subject:
- Must Do: High-weightage + familiar chapters
- Good to Do: Medium-weightage chapters you understand
- Can Skip: Low-weightage chapters that confuse you
This simple classification brings instant clarity.
Writing Practice Is NON-NEGOTIABLE
Especially for boards, students lose marks not because they don’t know the answers, but because they don’t present them well.
December must include:
- Daily 30–40 minutes of answer writing
- Practicing 3-mark and 5-mark questions
- Writing with headings, points, and diagrams
- Learning CBSE marking scheme expectations
This alone can improve scores by 10–15 marks.
Use Mock Tests to Decide What to Skip
Mock tests in December are not for judging intelligence; they are for decision-making.
After each mock:
- Identify weak chapters
- Decide whether to improve or skip
- Track time management
- Check presentation mistakes
Mocks tell you where to invest time and where not to.
Common December Mistakes Students Make
Avoid these at all costs:
- Studying everything every day
- Panicking after low mock scores
- Changing strategy every week
- Overloading with multiple books
- Ignoring rest and sleep
December needs discipline, not desperation.
