Every one of these also opens inside the past-paper builder, progress tracker and the AI tutor — look for the Tools button in the bottom corner, or press Alt + T. You never have to leave a question to look something up.
Whiteboard
Your own notebooks or an infinite canvas: real pens, shapes that snap, a ruler, protractor and compass for constructions, stickers, pasted images and past-paper questions. Saved to your account and exported as a PDF.
NewScientific calculator
Full scientific keypad with DEG/RAD, memory and a running history. Tell it your subject and it warns you when the paper you are practising is non-calculator — then locks itself if you want to train properly.
LiveFormula sheets
169 formulas across Maths, Physics and Chemistry, each marked Given in exam or Must memorise. IGCSE Physics provides nothing at all — this shows you exactly what that means.
LiveGraph plotter
Plot quadratics, cubics, reciprocals and trig curves. Drag to pan, scroll to zoom, hover to trace — and it reads off the roots and turning points in view.
LiveGraph sketching guide
Master graph shapes, asymptotes, and coordinate calculations. Includes step-by-step notes on sketching quadratic and cubic curves, and finding cubic equations from given graphs. For O Level, IGCSE & A Levels.
NewCommand words
State, Describe, Explain, Suggest — Cambridge's own definitions for your syllabus, what each one is really asking for, and real past-paper questions using them.
LivePeriodic table
The Cambridge table with the exact relative atomic masses printed in your exam paper, plus a mole calculator that parses formulas like Ca(OH)₂ and CuSO₄.5H₂O.
LiveNumber bases & logic
Denary, binary, hex and octal with the place-value working shown, two’s complement step by step, and truth tables with every intermediate column — where the marks actually are.
LivePseudocode runner
Write Cambridge pseudocode and run it. Errors come with the line number and a suggested fix, it flags Python habits creeping in, and it builds the trace table for you.
LiveGrade calculator
Enter your paper marks and predict your overall grade using official Cambridge grade thresholds and component weightings.
NewGrade thresholds history
Visualise how Cambridge grade thresholds and boundaries have changed over the last 10 years to spot syllabus trends.
