In addition, 41% of parents for these students have a degree level education.


Pie Chart1 - Lunch Analysis

Both female & male students follow the same overall ratio (1:3), although ethnic group A sees an increase in free/redeuced lunches at 40%.

In summary, there may be a case that an impecunious student may struggle with achieving better exam results.
