Common Mod (usually Term 4 2024) - as name suggests, shared with standard. You learn the same ideas and concepts of 'Texts and Human Experiences', but your assessment task and exam paper on the same topics are likely to be different (not easier or harder, just different)
Mod A (usually Term 1 next year) - Textual Conversations. Study of two texts telling the same 'story', one old text and one contemporary text, and the study of how the author of the second text considers the purpose of the author of the first text and retains, omits, subverts, reimagines, parodies various elements etc. There quite a few prescribed text pairs for this module your school can choose (you can see them on the NESA website), and you are forced to study the text pair your school chooses even if you like/are interested in another one and de facto forced to use this in your exam.
Mod B (usually Term 2 next year) - Critical Study of Literature. Study of a text and the author's purpose/intent in conveying messages for a bigger, deeper idea. There quite a few prescribed texts including films for this module your school can choose (you can see them on the NESA website), and you are forced to study the text your school chooses even if you like/are interested in another one and de facto forced to use this in your exam.
Mod C (usually Term 2/3 next year) - narrative writing, discursive writing, imaginative writing and informative writing skills and technqiues. While there are prescribed texts, you are not really forced to study a 'given' one for the exam - you can choose (might be the case for assessment), and you are given free choice in the exam on what prescribed text to use - they may not even ask for a prescribed text in this module, as was the case this year in the HSC. Arguably the most liberal one, but you need to familiarise yourself with how to write a good persuasive, imaginative, discursive AND informative as the exam can ask for either one, two or three of this four. Until 2024, everyone was lucky in that imaginative was always included - not anymore.
