“You’ve worked hard at that since your last assessment,” he said instead. “Yes, sir. Although I didn’t really understand it until Rafe explained about compound feedback. Once I understood that, the rest was simple.

Rafe said I should concentrate on getting the ideas right first.” “When you’re ready to try the maths, tell me and I’ll start you off. Or ask Rafe, if you want.” “I’ll do that, sir.” Churi had moved forward to the edge of his seat in nervous anticipation of Joshim’s verdict.
