Additionally, there is often a component of Science Pedagogy / Teaching Methodology for science teachers (how to teach science effectively, assessment in science, experiments, laboratory methods, etc.). Some syllabus versions include this as part of the “Subject Concerned” or as a sub-part. The “indicative syllabus” given by DSSSB (Post Code 806-24) would clarify how much pedagogy is included.

Official Indicative Syllabus and Important Notes

• DSSSB’s official site provides an Indicative Syllabus for Post Code 806-24 (TGT Natural Science / Physical Science) under DOE & NDMC. This is the reference for what the board expects.

• The syllabus above is compiled using multiple recent sources that describe the 2025 pattern and topic list.

• Because the syllabus is “indicative,” the exact questions may vary (some overlap, some omitted). Use this as your core guide, and also solve previous year question papers to understand what types of questions are being asked.

Best Resources to cover DSSSB TGT Natural Science Syllabus 2025

Recommended Books / Print Resources

These are books (and guides) that are aligned (or can be aligned) with the DSSSB TGT Natural Science syllabus. Use them as core study materials, supplemented with NCERTs and past year questions.

Study tip: Use the guides/book that cover both conceptual explanation + MCQs + solved papers. After finishing theory, practice past year questions.

Video / Online Lectures & YouTube Channels

Videos help in conceptual clarity (especially in topics you find tough). Some that are especially helpful:

You can also search for lectures on Pedagogy of Science and Science Teaching Methodology on YouTube or educational platforms like Unacademy, Gradeup, etc.

Online / Test Series / Mock Exams & Practice

• Use test series from platforms like Adda247, Testbook, Gradeup or Mentor365. They often simulate the actual DSSSB exam pattern.

• Solve as many past year question papers (PYQs) as possible. Use the guides that include solved papers.

• Use topic-wise quizzes / MCQ banks to continuously test your knowledge.

Study Plan & Strategy

Here’s a sample schedule and approach:

1. Divide the syllabus into small modules (e.g. in Physics: motion, work/energy, heat, electricity; in Biology: cell, human systems, environment, genetics, etc.)

2. Daily studies: pick one or two modules, read the theory, watch a video lecture, then solve 20–30 MCQs.

3. Weekly revision: set one day per week to revise all modules covered in that week.

4. Mock test every 15 days: simulate exam conditions, analyze mistakes.

5. In last 2–3 weeks, focus more on pedagogy + weak topics + revision notes + shortcuts.

6. Manage time & accuracy (since negative marks exist).
