PROBLEMS ARE COLOUR-CODED ACCORDING TO THEIR LEVEL
Welcome to the AMT Sandpit, an environment designed for you to have fun with new problems and techniques. Choose problems by your age, their category or difficulty (watch out - three-chilli problems are mentally spicy!). You can request up to two tips per question, but the more tips you need the fewer points you score. This is a beta product, so don't forget to fill out our survey below!
