From live chat with Cambridge Assessment Customer support 22 May 2018 Matt Berkley Hello - it seems that Cambridge exam material claims to have information on safe water in poor countries and that the 1990-based "MDGs" were established in 2000. Those seem to me to be clear errors, though widely believed. ... [Cambridge] Are you referring to a particular syllabus? Matt Berkley All relevant exam papers and specimen papers seem to make the errors, dating back many years. For example, O Level Environmental Management question paper 2017, question 2 on safe water. The burden of proof would seem to be on Cambridge. [Cambridge] I will certainly pass your comments through to our assessment team for their attention Matt Berkley Thank you. May I take it that the assessment team will respond? [Cambridge] I am not sure, I will pass your contact details on to them howeer
