What Is New in the Computer Science Sample Paper 2027?
Compared with the 2026 sample paper (session 2025-26):
- No change in pattern – same 37 questions in five sections (A 21×1, B 7×2, C 3×3, D 4×4, E 2×5), 70 marks, 3 hours and identical General Instructions as the 2025-26 paper.
- Internal choice is in the same 10 places as in 2025-26 (Q22, Q24, Q25, Q27, Q28, Q29, Q31, Q32, Q34 part IV, Q37 part V).
- Paper footnote changed from ‘the assessment scheme of the Academic Session 2024-25 will continue in the current session i.e. 2025-26’ to ‘There is no change in the Question Paper Design and Assessment Pattern for Academic Session 2026-27’.
- Both papers are 8 pages.
Questions from the Computer Science Sample Paper 2027
Two questions from the 2027 paper, to show the level:
- Section A, 1 mark: What will be the output of the following Python statement: print(25+100**1**3/5)
- Section C, 3 marks: A list of books is given as B = [(“Machine Learning Basics”, 550), (“World Geography”, 450), (“Wonder World”, 140), (“AI Revolution”, 750)]. Write user-defined functions on a stack named Books: I. Push_element() – push only books whose price is more than 250; II. Pop_element() – pop and display the items, then display “Stack Empty”.
CBSE Class 12 Computer Science Marking Scheme 2027 (Solutions)
The 2026-27 marking scheme gives the correct option/output for every Section A question and model Python programs and SQL queries for the rest, with a step-wise ½-mark break-up for coding questions (e.g. ½ for function header, ½ for opening the file, marks for logic, ½ for calling/printing; for Q35 ½ each for import, connection and cursor objects, 1 for the query, 1 for execute with commit, ½ for closing). Outputs for Q32 B are shown as result tables. Check your answers against it after you solve the paper.

How to Score Well – Tips from the 2027 Paper
- About a third of Section A is output prediction – practise operator precedence (e.g. 25+100**1**3/5 = 45.0), negative-step slicing (‘Drone Expo'[-2::-4] = ‘peD’), split(), random.randint/randrange ranges and local vs global variable errors.
- File handling carries heavy marks: a text-file function (Q29, 3 marks), CSV append/read functions (Q33, 4 marks) and binary-file append and update with pickle (Q36, 5 marks) – learn the standard patterns, including try/except EOFError for reading binary files.
- Practise SQL on given tables: GROUP BY with HAVING, DISTINCT, LIKE ‘%an%’, ORDER BY … DESC, IN, joins and Cartesian product (Q32, Q34), plus a Python–MySQL update program with commit() (Q35).
- For the 5-mark networking case study (Q37), be ready to choose the server location (block with most computers), topology, repeater placement (links over 100 m), switch placement and the cable for a long-distance wired link (optical fibre).
- For MCQs, write the text of the correct option along with the letter, as the General Instructions require.
- Solve the 2027 paper in one sitting with a timer, check it with the marking scheme, then solve the 2026 paper a few days later.
