In general, Education Perfect content is not case sensitive. The only exceptions to this rule are when correct capitalisation is specifically required as part of the answer, i.e. learning a non-case sensitive answer would be incorrect. For example, because German nouns are always capitalised, German translation lists are case sensitive. However, when translating from German to English, case sensitivity does not apply (even for proper nouns in English).
Additionally, any content within a Smart Lesson has the ability to be case sensitive - for example for English or ESOL when covering proper nouns.
