CBSE Class XII Computer Science Tips: “Stay systematic while debugging”

As the CBSE Board Examinations approach, Class 12 students are looking for effective ways to score well in Computer Science. A smart CBSE Class 12 board exam strategy can make all the difference — especially when it comes to programming logic, syntax accuracy, and time-management tips for CBSE board exams.

To help students prepare better, Mr Pankaj Ahuja, Head of Department – Computer Science, Apeejay School, Pitampura, shared expert insights and last-minute CBSE board exam tips.

Paper Format:

1. The question paper will contain 37 questions.

2. All questions will be compulsory. However, internal choices have been provided in some questions. Attempt only one of the choices in such questions.

3. The paper will be divided into 5 Sections- A, B, C, D and E.

4. Section A will consist of 21 questions (1 to 21). Each question carries 1 Mark.

5. Section B will consist of 7 questions (22 to 28). Each question carries 2 Marks.

6. Section C will consist of 3 questions (29 to 31). Each question carries 3 Marks.

7. Section D will consist of 4 questions (32 to 35). Each question carries 4 Marks.

8. Section E will consist of 2 questions (36 to 37). Each question carries 5 Marks.

9. All programming questions are to be answered using Python Language only.

10. In-case of MCQ, the text of the correct answer should also be written.

Build Strong Programming Logic

According to Mr Ahuja, the best way to strengthen programming skills is through regular practice. “Students must consistently practice questions taught in class along with assignments and projects. Logic-building comes only with hands-on practice.”

He emphasises solving NCERT exercises, CBSE sample papers, and past year papers as part of the best revision plan for CBSE Class 12 exams.

Avoid Common Programming Mistakes

Students often struggle with switching between Python and MySQL. “Python is case-sensitive and indentation defines the code structure. Also, MySQL queries must always end with a semicolon,” he explains.

He points out that file operations also confuse students since “the logic for text, binary and CSV files differs fundamentally and is not interchangeable.” Identifying such common mistakes to avoid in CBSE Class 12 exam ensures better accuracy.

Debugging & Revision Strategy

He suggests a calm, structured approach to error correction, “Stay systematic while debugging. Prepare well and review your work before final submission.”

During last-minute revision for CBSE Class 12, he recommends writing code in pencil first and then neatly finalising it.
