What Is Artificial Intelligence?
This course provides a foundational overview of artificial intelligence, covering its history since 1956, core goals like problem-solving, and primary techniques including formal logic and artificial neural networks. Students will also explore modern applications such as deep learning and generative transformers, alongside the ethical and societal discussions surrounding AI safety.
AI Automation for Everyday Work
Learn to hand the repetitive parts of your schoolwork and everyday tasks to AI, and keep the decisions for yourself. This beginner course explains what automation really means, how to tell repeated work from judgment work, and why language models changed what can be automated. You will learn to write prompts as clear instructions, give the model context and examples, and ask for output you can actually use. Then you will build real automations for flashcards, writing and summarizing, spreadsheets and data, and chain steps together into a workflow. Three quizzes check your understanding along the way. No coding needed.
Fractions
In this course, students learn what a fraction is: a part of a whole, like a slice of pizza. They’ll learn what the numerator (top number) and denominator (bottom number) mean, recognize fractions from pictures, compare two fractions to find the bigger one, and add simple fractions. This course is for students in grades 3 to 5. They only need to know how to count and do basic division
Probability for Beginners
This course covers the fundamental mathematical principles, historical evolution, and rules of probability theory. Students will explore core concepts including numerical measures between 0 and 1, independent events, and complementary probability calculations.
The Constitution of India
The Constitution of India is globally recognized as the longest written national constitution and serves as the country's supreme legal document. Formulated over nearly three years by a dedicated Constituent Assembly, it officially took effect on January 26, 1950.
How Digestion Works
This course covers the comprehensive structure and function of the human digestive system, including the gastrointestinal tract and accessory organs. It explains the three stages of digestion and how mechanical and chemical processes break down food for nutrient absorption.
The Water Cycle
This course explores the unending movement and continuous phase changes of water across Earth's oceans, atmosphere, and land. Students will learn about key physical processes such as evaporation, condensation, and precipitation, as well as how human activities and climate change impact global water systems.
The Indian Monsoon
This course explores the atmospheric mechanisms, scientific theories, and geographic factors that drive the South Asian monsoon. Students will also examine the monsoon's social, economic, and environmental impacts across the Indian subcontinent.
Calculus Foundations
Learn calculus from the ground up. Functions, limits, continuity, derivatives, integrals, and differential equations — every lesson explained with clear, everyday examples. With 17 video lessons and 6 quizzes, build a complete understanding of the mathematics of change. No prior experience required.
Foundations of Personal Finance
Students will learn the foundations of how to track their income and expenses, build a simple budget using the 50-30-20 rule, save an emergency fund, use banking and digital payments safely, avoid high-interest debt traps, and take their first steps into investing. Clear and practical — by the end the student will have knowledge on how to take real control of their money.
