Cambridge IGCSE Combined and Co-ordinated Sciences Teacher's Resource CD-ROM (Cambridge International IGCSE)

This CD has useful material to help teachers facilitate this course. HOWEVER the DVD ROM does not work on new mac computers running on Catalina onward. I have had to resort to using my husbands dinosaur of a Windows computer to access the files which is inconvenient but thankfully he has the computer, otherwise it would have been a wasted purchase. I have the same problem with the CD from the student's textbook but all the disks worked on my old mac (running on Mountain Lion) before it crashed...

useful.
