Survival Spanish: Spain Edition 🇪🇸

Planning a trip to Spain? Whether you're ordering tapas in Madrid, asking for directions in Barcelona, or checking into your hotel in Seville, this course will help you build the confidence to communicate in real-world travel situations.

Survival Spanish: Spain Edition is a beginner-friendly, conversation-focused course designed for travellers who want to quickly learn the essential Spanish phrases and responses needed to navigate airports, restaurants, shops, transportation systems, and everyday interactions while abroad.

Instead of memorizing long vocabulary lists or diving deep into grammar rules, you'll learn how to speak and understand practical Spanish through engaging travel missions that simulate real-life situations you’re likely to encounter during your trip.

Throughout the course, you'll complete interactive challenges, respond to realistic dialogue prompts, and earn digital travel stamps as you unlock new destinations — from the airport to the café, the hotel, and beyond.

By the end of this course, you will be able to:

  • Greet people and introduce yourself politely
  • Ask for directions and understand simple responses
  • Order food and drinks at cafés and restaurants
  • Check in at hotels and request basic services
  • Ask questions while shopping or using transportation
  • Handle common travel situations with confidence

No prior knowledge of Spanish is required — just a willingness to practice and have fun!

Pack your bags and get ready to Speak Spanish with Confidence on your next adventure.

Lagrange Operators: Optimization with Constraints

Finding maximums and minimums when rules must be obeyed

Course Description

This course introduces Lagrange multipliers (often called “Lagrange operators” by students), a powerful technique used to optimize functions subject to constraints. Students develop intuition through geometry, gradients, and constraint curves before mastering the formal method and building problem-solving fluency. The course balances conceptual understanding with algebraic precision and includes real-world applications in physics, economics, and engineering.

Target Audience

  • Grade 11–12 students in advanced mathematics
  • Students in IB Math AA HL / AP Calculus / first-year university preparation pathways
  • Physics, economics, and engineering-bound students who want stronger optimization tools

Prerequisites

To succeed in this course, students should already be comfortable with:

  • Partial derivatives
  • Gradients and level curves
  • Optimization of single-variable functions

💡 Tip: If you’re a bit rusty on gradients or partial derivatives, you can still take this course— just plan to review those topics during Unit 1.

🌈 The Physics of Diffraction: Slits, Gratings, and Patterns

See how light bends, spreads, and forms brilliant fringes — step by step.

When light passes through a narrow slit or a diffraction grating, it doesn’t behave “straight-line simple” anymore. This focused course guides you through single-slit diffraction, double-slit interference, and diffraction gratings using clear visuals, intuitive explanations, and worked examples.

  • 🌊 Understand diffraction as wave spreading (when gap size ≈ wavelength)
  • 🔬 Explain single- and double-slit patterns (maxima, minima, fringe spacing)
  • 📐 Use diffraction equations to calculate wavelength and slit/grating spacing
  • 🌈 Connect diffraction gratings to real spectroscopy & modern tech

🧩 Fractions, Ratios & Percentages — Made Calm

Understand the ideas clearly, practise step-by-step, and build confidence.

A short, guided mini-course that helps you make sense of fractions, ratios, and percentages — without rushing, guessing, or memorising tricks.

  • ✅ Simplify & compare fractions
  • ✅ Ratios (and what they actually mean)
  • ✅ Percentages as “out of 100” + conversions
  • 🔐 Final Vault Challenge + badge
