Clear notes, live HTML & Python playgrounds, and chapter tests. Free forever.
🧪 Simulators
Convert number systems and flip logic gates live — don't just read the truth table, build it.
🐍 Real Python
Run Python in the browser, no install — see variables and loops execute step by step.
🇮🇳 Bilingual
Explanations in English and Hindi, tuned to the CBSE 083 syllabus.
📝 Exam-ready
CBSE theory, chapter tests and projects mapped to the 70+30 marks pattern.
Computers & Networks
Operating systems & files, computer networks (devices, topologies, media), the internet and cyber safety.
Computers & Networks
What an OS does and its types (single/multi-user, multitasking, real-time); CUI vs GUI; files, folders, paths & extensions; open-source vs proprietary OS.
Why networks; devices (NIC, hub, switch, router, modem); types (PAN/LAN/MAN/WAN); topologies (star/bus/ring/mesh/tree); wired & wireless media; protocols.
Client-server vs peer-to-peer; internet connections (broadband/cellular/satellite); cloud computing; firewalls, phishing & identity theft; IPR & software licences.
Databases (MS Access)
Relational databases — tables, primary keys, relationships, queries, forms and reports.
Databases
Why databases beat flat files; the MS Access objects; data types; creating tables in Design & Datasheet view; primary keys; records; table relationships.
Build queries (wizard & design view) with criteria and sorting; design forms for easy data entry; and generate formatted reports for printing.
Spreadsheets (Excel)
Advanced Excel — functions, sorting & filtering, data validation, conditional formatting and charts.
Web Development (HTML & CSS)
Build web pages with HTML — text, lists, images, links, tables & forms — and style them with CSS. Live preview.
Web Development
The HTML skeleton; headings, paragraphs, strong/em; ordered & unordered lists; images; and internal & external hyperlinks — with a live preview.
Build tables (table/tr/th/td) with borders & spacing, merge cells with rowspan/colspan, and create simple forms (text boxes, checkboxes, buttons) — live.
Why CSS; inline, internal & external styles; CSS syntax (selector, property, value); and styling text, backgrounds, borders & margins — live preview.
Coding & Apps
Algorithms & flowcharts, real Python (run live), and an intro to building mobile apps.
Coding & Apps
Algorithms & flowcharts; Python (IDLE, interactive vs script); variables & data types; operators; input() & typecasting; and if / if-else / if-elif-else — run live.
Native/web/hybrid apps and their uses; visual app builders (MIT App Inventor / blockly); designing a UI (buttons, labels, images); and click-action logic blocks.
