Just to show how unfair the system is, a bright girl in my daughter's class scored 140, 139, 116 and was judged not suitable for grammar school. This is despite having a score that is 35 marks above the pass mark! The head teacher appeal also failed on the grounds that her work in the lowest-scoring subject (Maths) was not up to grammar school standard.... seems mad to me. There are girls who are clearly less able getting assessed suitable when she is not.
My DD also missed out in a similar but less dramatic way, with an aggregate of 365 including a 140 for VR but two scores below the 117 cut-off.
This does seem madness, especially when other tests (Medway) have an aggregated score system with no minimum in any area. This can mask a weakness in a particular area.
