Examiners report
Another straightforward question that still only saw a few candidates able to achieve full marks. A number of responses crossed clusters. Most candidates understood the concept of second generation robots well, but many were simply listing characteristics rather than developing an explanation of an advantage. Many candidates achieved 1-2 marks and a few were able to achieve full marks, while a number also compared first and second generation robots.
