Languages

A question is one logical question with any number of language versions. Options share stable ids across languages, so a student answering in Hindi is graded by exactly the same key as one answering in English.

How it flows

1. Add each question in the languages you teach (the bank form has language tabs; imports and agents pass a translations array).
2. A test declares its conduct languages (e.g. English + हिन्दी).
3. Publish blocks until every attached question covers every conduct language — the error lists exactly which question is missing which language. Random pooling only ever picks questions that already qualify.
4. Students pick a language at the start and can switch on any question (the JEE pattern) — their answers carry over, because answers are option ids, not text.

Notes

• fill_blank can carry per-language accepted answers; grading accepts the union, so "Delhi", "दिल्ली" and "Dilli" can all be right.
• Language codes are ISO-639-1: en, hi, bn, ta, te, mr, …
