We are pleased to inform you that you have been accepted for remedial Arithmancy training.
Dark times are upon us. Dementors are gathering at the edges of our vision. They feed on hesitation. To drive them back, you must cast your spells (answer the equations) quickly and accurately.
Should you struggle, look to the stars for guidance. If you succeed, you will be rewarded with Galleons to spend on supplies in Diagon Alley.
