Week by week
A week opens every Monday at midnight UK time, starting Mon 2 Nov. Its episodes, dataset and files appear here the moment it opens.
How to open the files

Opens in Excel or Google Sheets with a double click. Python reads it with pd.read_csv("orders.csv").
Database scripts
Install MySQL Community (free). In MySQL Workbench choose File, Open SQL Script, pick the file and press the lightning bolt.
Guides and answers
Questions first, answers at the back. Try each one yourself before you look.
Practice packs use synthetic data made for AnalytixAI, free to use and share. Week projects use public datasets (for example Olist, OpenAQ and the UCI Online Retail data). Those keep their original licences and are linked to their source.
