Great tips. My WSET level 3 has been converted to study at home during lockdown. I read my text book on a topic eg: Burgundy, and write notes. Then I'll read another 1 or 2 text books, writing notes, then watch a you tube video or 2. I do this over 4 to 7 days. The next week, I rewrite all the notes into a large blank art portfolio and add pictures (maps) or other illustrations, combining all information from all formats. eg: Burgundy - CLIMATE, TERROIR etc. I'll then review the portfolio before exams.
