There is an updated version of the H2 Economics syllabus since 2015 in the SEAB website. You can go to the official SEAB website and download for your own reading. Did a quick glance through and below are the changes I discovered.
- Bullets have changed from square to circle.
- Page 5 comments missing a square close bracket. Used to be there.
- Recommended reading list updated with additional page listing supplementary text and reference sources.
The rest of the important content is exactly the same word for word as per previous syllabus.
