Practice real IELTS tasks and get instant band scores with examiner-style feedback on Writing, Speaking, Reading, Listening and Mock Test Simulation. 7 Days of Free usage included!
Practice real IELTS tasks and get instant band scores with examiner-style feedback on Writing, Speaking, Reading and Listening. Free mock test included — no credit card.
Practice real IELTS tasks. Get detailed feedback on every answer. Track your band score over time. Not just scores — the tools that turn every mistake into your next gain. Your grammar and vocabulary errors are collected automatically, then each one routes to the lesson that fixes the rule behind it — not just that sentence. Highlight a word or phrase anywhere and get its meaning and a translation in your own language, then keep it for spaced-repetition practice. The study found that ubiquitous smartphone usage has altered how people consume information. Play your speaking answer back with its pronunciation score, pace and pauses — then re-read your essay with the marks still on it, grammar…from sharply.courses

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
