45-Day CUET Strategy
Here’s a structured
6-week CUET (Mechanics) study plan that balances
NCERT fundamentals, mock tests, and revision cycles. Adjust based on your pace and strengths.
Week 1-2: Foundation Building (NCERT + Concepts)
Goal: Cover NCERT Class 11 12 Mechanics thoroughly (Units: Motion, Laws of Motion, Work-Energy, Rotational Motion, Gravitation).
Daily Plan (3-4 hours/day):
- Morning (1.5 hours):
- Read 1-2 NCERT chapters + highlight key formulas/concepts.
- Solve 10-15 NCERT examples/exercises per topic.
Focus areas:
- Week 1: Kinematics, Newton’s Laws, Friction.
- Week 2: Work-Energy Theorem, Circular Motion, Rotation.
Afternoon (1 hour):
Practice 5-10 numerical problems from reference books (e.g., HC Verma/DC Pandey) for application.
Evening (1 hour):
- Revise formulas + make flashcards.
- Solve 5 conceptual MCQs (use CUET-specific question banks).
Weekend (Sat/Sun):
- Take a
30-question topic-wise quiz (e.g., Motion + Laws of Motion).
- Analyze mistakes and revisit weak areas.
Week 3-4: Advanced Practice + Mock Tests
Goal: Strengthen problem-solving and speed via mocks.
Daily Plan (4-5 hours/day):
- Morning (2 hours):
- Cover remaining topics (Gravitation, SHM, Elasticity).
Solve 15-20 advanced problems (focus on CUET-level difficulty).
Afternoon (1.5 hours):

Review solutions + note recurring errors.
Evening (1 hour):

2 hours analyzing the mock (accuracy, time management).
Week 5-6: Revision + Grand Mocks
Goal: Maximize retention and exam readiness.
Daily Plan (5-6 hours/day):
- Morning (2 hours):
- Rapid revision of all topics (use mind maps/summary notes).
Solve 10-15 high-yield MCQs (e.g., past CUET/JEE Main questions).
Afternoon (2 hours):
Alternate between:
- Full-length mock (Mon/Wed/Fri).
- Topic-wise speed tests (Tue/Thu/Sat).
Evening (1-2 hours):
- Review mock answers + revise weak areas.
- Practice 5-10 assertion-reason questions daily.
Last 3 Days:
- Light revision only.
- Focus on
formulas, common traps, and time-bound practice.
Key Tips:
- NCERT First: Ensure 100% clarity on NCERT concepts before jumping to advanced books.
- Mock Tests: Gradually increase frequency (1/week → 3/week).
- Error Log: Maintain a notebook for mistakes and revise it weekly.
- Time Management: Allocate 45-60 seconds per MCQ in mocks.
Resources:
- NCERT Physics (Class 11 12).
- HC Verma (Vol. 1) / DC Pandey (Objective).
- CUET-specific mock test series (e.g., Oswaal/Arihant).
Stick to this plan, and you’ll see steady progress! Adjust timings based on your schedule. Good luck! �
