Complete Guide to CBSE Internal Assessment and Practical Marks Optimization

Understanding CBSE Internal Assessment Structure

The Central Board of Secondary Education (CBSE) has integrated internal assessment into its evaluation system to ensure students are continuously engaged with learning. Typically, 20% of the final board score comes from internal assessments, while 80% comes from the year-end board exam.

Internal assessment includes components like periodic tests, notebook submission, subject enrichment activities, and practical work, depending on the subject. These are not just marks on paper — they reflect classroom engagement, consistency, and real-world application of concepts.

Subject-wise Practical Examination Requirements

Subjects like Science, Mathematics (in Class 10), Computer Applications, and Home Science have a practical component that contributes to final board marks. Here's a breakdown:

• Science (Classes 9 & 10): Practical exams include experiments, viva voce, record keeping, and written work.

• Mathematics (Class 10): Internal marks include periodic assessments and math lab activities.

• Social Science: Project work (such as disaster management or economics-based reports) contributes to internal marks.

• English/Hindi: Assessment includes speaking/listening tasks and creative writing exercises.

Strategies for Consistent Performance in Unit Tests

Periodic tests (also called unit or cycle tests) are a major internal component. These tests usually happen 3 times in an academic year. To score well consistently:

1. Maintain a study schedule aligned with your school’s test calendar

2. Revise each week’s topics proactively instead of last-minute cramming

3. Practice from Edzy’s chapter-wise question banks for targeted preparation

4. Review errors from past tests and avoid repeating them

Project Work Planning and Execution

Projects are an opportunity to demonstrate deeper understanding. Whether it's a geography model or an economics survey, good projects stand out through:

• Clear structure: introduction, data collection, analysis, conclusion

• Use of visuals like charts, graphs, and hand-drawn maps

• Original work — avoid copy-paste content from the internet

• On-time submission and neat presentation

Discuss your topic with teachers early and seek feedback at different stages. Edzy also provides templates and guidance for project execution inside the app.

Lab Practical Preparation and Execution

Practical lab work is not just about performing an experiment, but also about following proper procedure and recording observations accurately. Here’s how to prepare:

1. Revisit your practical manual and understand each experiment’s aim

2. Practice drawing diagrams and labeling them properly

3. Memorize common formulas and calculations used in your experiments

4. Ensure your lab record book is complete, signed, and neat

Most importantly, don’t miss your school’s mock practical sessions — they mirror the final exam and help reduce nervousness.

Viva Voce and Oral Examination Techniques

Viva sessions test your conceptual understanding and communication clarity. They may be conducted during practicals or as part of language assessments. To ace it:

• Prepare short summaries for each experiment or project

• Review key terms and definitions (especially from the practical manual)

• Practice answering aloud with a friend or family member

• Be honest if you don’t know an answer — show willingness to learn

"Confidence comes from preparation — not perfection."

Maintaining Records and Portfolios

Several subjects require students to submit portfolios, journals, or lab records. These must be updated throughout the year. Tips for a strong submission:

• Use one notebook or folder per subject for clarity

• Include dates, headings, and page numbers

• Add reflective notes or learning outcomes at the end of entries

• Use diagrams, photos, or printouts to enrich your content

Schools often assess portfolios not just for content but also consistency and effort. Don’t wait till the deadline to start yours.

Common Mistakes and How to Avoid Them

Many students lose easy internal marks due to negligence or miscommunication. Avoid these common pitfalls:

1. Ignoring internal marks because “they don’t matter” — they do

2. Missing deadlines for submissions and notebooks

3. Submitting incomplete projects or records

4. Memorizing experiments without understanding the process

Parents can help by tracking school communications, reminding about deadlines, and encouraging a balanced study approach.

Final Thoughts

CBSE’s internal assessment system is designed to promote consistent learning, not just final exam performance. By taking it seriously, students can secure marks that significantly boost overall percentages. With tools like Edzy's personalized study plans and project resources, making the most of internal marks is simpler and smarter than ever.
