Algorithms HQ vs GCSE Geography

A fun and didactic app to learn computer science algorithms! See how algorithms are working by watching an animation of their execution. Understand how data is manipulated as it is animated through an intuitive representation of its contents. Always know which line is executed in the pseudo-code, what are the values of the variables. Need to quickly refresh your memory? Just use the app as a quick reference on the main characteristics of each algorithm! Main features: - Execute a single instruction, or undo the previous one - Run, or rewind the algorithm until you decide to pause the execution - Adjust the speed of the animation - Best and worst case input data for sorting algorithms - Change the input data: size (up to 500), maximum value or data distribution (random, sorted, many duplicates, etc.) - For data structures, choose the next function to execute, or let a scenario choose for you, so you can see how the data structure evolves. - Landscape or portrait orientation This version contains the following algorithms: Linear Data Structures: - Linked Lists, including a view on memory - Queue - Stack Sorting algorithms: - Bubble Sort - Cocktail Sort - Gnome Sort - Insertion Sort - Quick Sort - Selection Sort More algorithms and more features are on the way!

GCSE Geography helps you study for GCSE (9–1) Geography, the UK exam taken at age 16, with exam-style questions, revision notes and a mock test. Choose your exam board when you first open the app: AQA (8035), Edexcel Geography B (1GB0) or OCR Geography B (J384). Topics, questions and the mock test then follow your course. It suits students in Year 10 and Year 11, and parents or teachers who want a structured way to study. WHAT'S INSIDE • AQA: 920 exam-style questions across 92 subtopics • Edexcel B: 820 exam-style questions across 82 subtopics • OCR B: 850 exam-style questions across 85 subtopics • A revision note for every subtopic, with diagrams, key terms and examples • A full explanation with every question, so you see why the right answer is right • A Mock Test that draws questions from across your course YOUR CASE STUDIES, NOT EVERYONE'S Every school teaches different case studies. Pick the ones your teacher uses, such as Nepal 2015 or Chile 2010 for tectonic hazards, Rio de Janeiro, Lagos or Mumbai for a city in a poorer country, or the Holderness or Dorset coast. The app hides the case studies you don't study, in topic lists and in the Mock Test. For AQA and Edexcel B you can also choose your options, such as hot deserts or cold environments (AQA) or your fieldwork (Edexcel B), or which UK landscapes you studied. Not sure yet? Leave it on "Not sure – show all" and you see everything. Changing a choice never deletes your progress. PHYSICAL, HUMAN AND SKILLS • Physical Geography: tectonic and weather hazards, climate change, ecosystems, rainforests, deserts and cold environments, and UK landscapes such as coasts, rivers and glaciated uplands • Human Geography: urban issues, development and the changing economic world, the UK economy, and resource management • Geographical Skills: atlas and OS maps (grid references, scale, contours and cross sections), photographs, satellite images and GIS, graphs and charts, choropleth, isoline and flow-line maps, averages and percentages, scatter graphs, fieldwork and issue evaluation MAP AND GRAPH SKILLS Skills questions come with their own maps, graphs and climate graphs, so you practice reading real values and patterns the way the exam asks you to. A note on the format: questions are multiple choice. The app helps you learn facts, case-study detail and skills, and spot common mistakes. It does not grade extended written answers, so keep practicing those on paper too. FREE TO TRY Part of every board's course is free, with its questions and the Mock Test on those questions: 120 free questions on AQA and OCR B, and 150 on Edexcel B. Case-study subtopics are part of the full version. UNLOCK EVERYTHING Unlock every subtopic, question, note and case study with: • a monthly, quarterly, 6-month or yearly subscription, or • a one-time lifetime unlock, paid once with no renewal Payment is charged to your Apple Account when you confirm the purchase.
