Common Mistakes – what did the examiners say? Foundation Tier           A significant number of candidates gained some credit on this question. Many found the total of £25 but were unable to deal with the 10% reduction in any way. Others tried to find 10% of each item separately but this also led to many computational errors. Careless arithmetical errors led some to lose marks.           Higher Tier           This was answered well with over three quarters gaining full marks. Many others scored 2 marks. Some basic arithmetical errors were made. Considering that the numbers involved were straightforward these were careless mistakes that should have been avoided.
