It was recently brought to our attention that the site which was hosting a lot of the images and PDF documents for Passy’s World of Mathematics got hacked, and there has been some very unsavoury advertising and spam present on some of our lessons.
We are slowly repairing the site, and doing work to host the images on our own server space. This could easily take us the next 30 days to fix all 190 lessons on this site. We thank you for your patience.
