❓ Important Previous Year Questions (PYQs) with Answers
Q1. What is the difference between a compiler and an interpreter?
Answer:
- A compiler translates the whole program at once.
- An interpreter translates line-by-line.
- Example: Python uses an interpreter.
Q2. Write a Python code to accept a number and print whether it’s even or odd.
pythonCopyEditnum = int(input("Enter a number: "))
if num % 2 == 0:
print("Even")
else:
print("Odd")
Q3. What is the difference between a list and a tuple in Python?
Answer:
- List is mutable, i.e., changeable.
- Tuple is immutable.
- List uses
[], tuple uses().
Q4. Name any two emerging technologies and explain.
Answer:
- AI (Artificial Intelligence): Simulates human intelligence in machines.
- IoT (Internet of Things): Network of physical objects that communicate via internet.
🎯 Class 11 Computer Science Preparation Tips
Follow this plan to maximize your score:
✅ 1. Make a Weekly Timetable
- Mon-Wed: Python theory + code practice
- Thu-Fri: Revise theory chapters (hardware, ethics)
- Sat: Solve PYQs and MCQs
- Sun: Weekly test or project work
✅ 2. Practice Python Daily
Use online editors like Replit, Google Colab, or IDLE to practice syntax and logic.
✅ 3. Make Your Own Flashcards
Create quick-reference cards for:
- Python functions
- List/tuple/dict differences
- Number system conversions
✅ 4. Don’t Ignore Theory
Many students focus only on coding. CBSE exams include many 1-3 mark theory questions.
❌ Mistakes to Avoid
- Ignoring Practical File – Your Python programs + documentation contribute to the final grade.
- Skipping Ethics Chapter – At least 5 marks are from “Society, Law & Ethics.”
- Cramming Code – Understand the logic instead of memorizing syntax.
- Not Practicing Output-based Questions – Boards love tricky output-based MCQs.
