Unit I: Computational Thinking and Programming – 2 – (80 Theory + 70 Practical)
- Revision of the basics of Python
- Functions: scope, parameter passing, mutable/immutable properties of data objects, pass arrays to functions, return values, functions using libraries: mathematical, and string functions.
- File handling: open and close a file, read, write, and append to a file, standard input, output, and error streams, relative and absolute paths.
- Using Python libraries: create and import Python libraries
- Recursion: simple algorithms with recursion: factorial, Fibonacci numbers; recursion on arrays: binary search
- Idea of efficiency: performance defined as inversely proportional to the wall clock time, count the number of operations a piece of code is performing, and measure the time taken by a program. Example: take two different programs for the same problem, and understand how the efficient one takes less time.
- Data visualization using Pyplot: line chart, pie chart, and bar chart.
- Data structures: lists, stacks, queues.
Unit 2: Computer Networks (CN) – (30 Theory + 10 Practical)
- Structure of a network: Types of networks: local area and wide area (web and internet), new technologies such as cloud and IoT, public vs. private cloud, wired and wireless networks; concept of a client and server.
- Network devices such as a NIC, switch, hub, router, and access point.
- Network stack: amplitude and frequency modulation, collision in wireless networks, error checking, and the notion of a MAC address, main idea of routing.
- IP addresses: (v4 and v6), routing table, router, DNS, and web URLs, TCP: basic idea of retransmission, and rate
modulation when there is congestion (analogy to a road network), Protocols: 2G, 3G, 4G, WiFi. What makes a protocol have a higher bandwidth? - Basic network tools: traceroute, ping, ipconfig, nslookup, whois, speed-test.
- Application layer: HTTP (basic idea), working of email, secure communication: encryption and certificates (HTTPS), network applications: remote desktop, remote login, HTTP, FTP, SCP, SSH, POP/IMAP, SMTP, VoIP, NFC.
Unit 3: Data Management (DM-2) – (20 Theory + 20 Practical)
- Write a minimal Django based web application that parses a GET and POST request, and writes the fields to a file – flat file and CSV file.
- Interface Python with an SQL database
- SQL commands: aggregation functions – having, group by, order by.
Unit 4: Society, Law, and Ethics (SLE-2) – (10 Theory)
- Intellectual property rights, plagiarism, digital rights management, and licensing (Creative Commons, GPL, and Apache), open source, open data, privacy.
- Privacy laws, fraud; cyber-crime- phishing, illegal downloads, child pornography, scams; cyber forensics, IT Act, 2000.
- Technology and society: understanding of societal issues and cultural changes induced by technology.
- E-waste management: proper disposal of used electronic gadgets.
- Identity theft, unique ids, and biometrics.
- Gender and disability issues while teaching and using computers.

CBSE 12th Class Computer Science Exam Pattern 2021
Marking Scheme plays a vital role in exam preparation time. It covers all required details about the question paper like how many marks each question carries and many more. From the below tabulated CBSE Class 12 Computer Science Python Exam Pattern 2021, you can easily understand which chapter contains a number of marks and the total number of marks to be gained by the students in the examination.
| Chapter Name | Theory marks | Theory periods | Practical periods |
|---|---|---|---|
| Computational Thinking and Programming – 2 | 40 | 70 | 50 |
| Computer Networks | 10 | 15 | … |
| Database Management | 20 | 25 | 20 |
| TOTAL | 70 | 110 | 70 |
12th CBSE Computer Science Practical Exam Pattern & Syllabus
Students of class 12 should aware of the practical exam pattern and provided important lab syllabus topics before they start preparing for the cbse class 12 computer science board exams.
| Area | Marks Allotted |
|---|---|
| Lab Test | 12 |
| Report file | 7 |
| Project | 8 |
| Viva voce | 3 |
| Total Marks | 30 |
A few of the sample lab assignments are listed below:
Python Programming:
- Recursively find the factorial of a natural number.
- Write a recursive code to find the sum of all elements of a list.
- Write a recursive code to compute the nth Fibonacci number.
- Read a text file line by line and display each word separated by a #.
- Read a text file and display the number of vowels/ consonants/ uppercase/ lowercase characters in the file.
- Create a binary file with a name and roll number. Search for a given roll number and display the name, if not found display the appropriate message.
- Create a binary file with roll numbers, names, and marks. Input a roll number and update the marks.
- Remove all the lines that contain the character `a’ in a file and write it to another file.
- Write a random number generator that generates random numbers between 1 and 6 (simulates a dice).
- Write a Python program to implement a stack and queue using a list data-structure.
- Take a sample of ten phishing e-mails (or any text file) and find the most commonly occurring word(s)
Database Management
- Create a student table and insert data. Implement the following SQL commands on the student table:
- ALTER table to add new attributes / modify data type / drop attribute
- UPDATE table to modify data
- ORDER By to display data in ascending/descending order DELETE to remove tuple(s)

Computer Science Project for CBSE Class XII
The aim of the class project is to create something that is tangible and useful. This should be done in groups of 2 to 3 students, and should be started by students at least 6 months before the submission deadline. The aim here is to find a real world problem that is worthwhile to solve. Students are encouraged to visit local businesses and ask them about the problems that they are facing. For example, if a business is finding it hard to create invoices for filing GST claims, then students can do a project that takes the raw data (list of transactions), groups the transactions by category, accounts for the GST tax rates, and creates invoices in the appropriate format. Students can be extremely creative here. They can use a wide variety of Python libraries to create user friendly applications such as games, software for their school, software for their disabled fellow students, and mobile applications, Of course to do some of this projects, some additional learning is required; this should be encouraged. Students should know how to teach themselves.
If three people work on a project for 6 months, at least 500 lines of code is expected. The committee has also been made aware about the degree of plagiarism in such projects. Teachers should take a very strict look at this situation, and take very strict disciplinary action against students who are cheating on lab assignments, or projects, or using pirated software to do the same. Everything that is proposed can be achieved using absolutely free, and legitimate open-source software.
