∫ dx: A-Level Maths Revision
Getting good at A-Level Maths takes one thing: deliberate practice. Not more notes. Not another YouTube playlist. Questions, done consistently, until the methods become second nature.
dx is built for exactly that.
Smart revision that adapts to you
dx tracks every question you rate as "needs work" or "partially got it" and brings it back at the right time - spacing reviews so you're drilling your weak spots, not wasting time on what you already know.
AI hints that teach, not spoil
Stuck on a question? Get a progressive hint that nudges you in the right direction without giving away the answer. Learn to think through problems, not just copy solutions.
