+## Overview
+This dataset consists of 2 json files named 'ielts_new.json' and 'ielts_old.json', which contain ielts questions and its corresponding answers for part 1 and part 2.
+
+'ielts_new.json': new IELTs topics for 2024 September-December.
+
+'ielts_old.json': remained IELTs topics for 2024 September-December.
+
+## Quality
+Since the dataset is analysed and generated by ChatGPT based on my own pdf file, the answer may be incomplete(only part of the sentence is extracted, leading to short answer). From my observation, generally 'ielts_new' is better than old one because answers are more complete, though 'ielts_old' has more data items.
