Samacheer Kalvi 100-Mark Paper Pattern
Tamil Nadu follows the Samacheer Kalvi unified curriculum. For SSLC, most major subjects follow a 100-mark theory paper (no separate practical marks deducted from theory).
Typical SSLC Paper Pattern
| Section | Question Type | Marks |
|---|---|---|
| Part I | Choose the correct answer (MCQ) | 15 × 1 = 15 |
| Part II | Answer in 2-3 sentences | 10 × 2 = 20 |
| Part III | Answer in 5-6 sentences | 10 × 5 = 50 |
| Part IV | Answer in detail (essay type) | 3 × 5 = 15 |
| Total | 100 |
Why this matters: The Part III questions carry 50 marks — half the paper. Mastering 5-mark answers is the single biggest lever for scoring high.
Practical Exam Schedule — SSLC
SSLC practical exams run from February 19 to February 26, 2027. These are conducted at school level.
| Subject | Practical Format | Preparation Tips |
|---|---|---|
| Science | Lab experiments + viva | Practice all prescribed experiments. Know the theory behind each. |
| Computer Science | Programming practical | Practice all programming exercises from textbook. |
Complete your practical records and lab journals by February 15 — schools require these before the practical exam.

How to Prepare Using the Date Sheet
Gap Analysis for SSLC
With exams from March 17 to April 12, you have roughly 27 days. Use the gaps between papers strategically:
| Gap Between Papers | Strategy |
|---|---|
| 1 day | Light revision only — formulas, key points, diagrams for the next paper. |
| 2-3 days | Day 1: chapter-wise revision. Day 2: solve 1 full model paper under timed conditions. Evening before: light review. |
| 4+ days | Day 1-2: deep revision of weak chapters. Day 3: full timed model paper. Day 4: formula sheet review. |
The HSC Advantage — Results Before SSLC
HSC results are expected on May 7, while SSLC results come on May 20. If you are a Class 10 student, your results come almost 2 weeks after Class 12 results. Use this time to plan your stream selection while waiting.
Using the Pre-Exam Period Effectively
- February 19-26: Practical exams. Divide your time between practicals and theory preparation.
- February 27 - March 16: This is your golden revision period. 18 days with no exams.
