Examiners report

This question was well answered on the whole, and most knew the symptoms of type II diabetes. It was noted that weaker candidates tended to write about blood sugar or sugar in urine rather than the more accurate term of glucose.

b.

Most answers listed dietary advice without any justification, and since this was an explain question, many gained no marks. There were few accurate descriptions of foods with low glycemic index, a term with which students were expected to be familiar, purely from general knowledge.
