those were many, but I think for that school it was a case of having 2 classes sitting for that exam, the previous year's results had been canceled and so they just took back all the kids in to resit the exams.

Everything has a downside. The number of students with Es has shot up from an average of 5K in previous years, to 33K this year. That is tooo large a number. What to do with them!.

Nothing is ever as it seems.
From this SlideShare, it is clear to see that http://www.slideshare.ne...on-essential-statistics

In Table 1, 52% of the candidates for KCSE 2016 exams are Male
But in Table 8, overall national grade summary, 52% of candidates' grades are Female [or 299,268 out of 571,161]

In fact table 1 shows Male column first, table 8 shows Female first. Implying an interchanging typo.

Could it be that one table reads 2016 and the other 2015?
