- Sentence Improvement & Ordering (20 Questions): Tests logical flow and paragraph organization.
Part B: General Knowledge (100 Questions - 400 Marks)
The GK section is divided into specific marks allotments as follows:
- Physics (100 Marks): General physics laws, optics, heat, electricity, sound.
- Chemistry (60 Marks): Atoms, chemical reactions, acids, bases, salts, properties of elements.
- Biology (40 Marks): Cells, human anatomy, diseases, vitamins, food cycles.
- History & Freedom Movement (80 Marks): Indian national struggle, British rule, global revolutions.
- Geography (80 Marks): Earth dynamics, climates, Indian crops, rivers, geography maps.

Part 3: 6-Month Structured Study Planner
A structured routine keeps you accountable. Here is how you should break down your 6-month timeline:
Months 1 & 2: Core Concept Mastery
Focus 70% of your time on building base concepts. Solve all NCERT problems for Class 11 and 12 Maths. Read Wren & Martin for English rules, and read Class 9 & 10 science textbooks. Do not rush to solve complete mock tests yet.
Months 3 & 4: Sectional Practice & Speed Work
Begin chapter-wise practice on the **SenaPrep app**. Check your accuracy report for each chapter. Target your weak areas (like Calculus or Prepositions) by reviewing concise revision notes. Solve at least 5 years of Previous Year Papers (PYQs).
Months 5 & 6: Full-Length Mocks & Revision
Take 2 full-length mock tests every week in real-time exam shifts. Analyze your time-management. Use the SenaPrep All-India Leaderboard to see where you stand and review detailed solutions for every incorrect answer.
