Re: CXC Integrated Science exam guide: Section B: Safety hazards

I teach CXC Integrated Science and I use this guide as a syllabus. Its much more concise than the syllabus. I would very much like if there was an option to download or print all of this.

Glad you like it

Hi guest,
Glad you like our Integrated Science subject guide. Actually we do supply "printer friendly" versions of all our resources, however, you would need to be a member of the community to access this. Why don't you join? Its free.
