The number of KCSE candidates with A (plain) have increased to 315 compared to 2017 when only 142 attained the top mark.
However, the number of candidates with direct entry to university remains low as only 90,377 scored C+ and above in the just released results.
This translates to 13.77 per cent of the 660,204 candidates who sat the examination and can be interpreted that 567,827 candidates – an equivalent of 86.23 per cent, will have to seek admission in other tertiary colleges and vocational schools.
The results, unveiled by Education CS Amina Mohamed, indicate that some 201 boys scored A plain compared to 114 girls.
At least 2,179 boys scored A- while 5,157 others scored B+ compared to 1,238 girls who scored A- and 3,111 that attained the B+ grade.
Overall, 315 candidates scored A plain, 3,417 (A-), 8,268 (B+), 16, 403 (B plain), 26,156 (B-) while 20,131 scored C+ (plus).
In 2017 KCSE examination, out of the 611,952 candidates who sat the exam, only 70,073 qualified to join university.
Education CS Amina Mohamed while releasing the results said though boys had performed well in some 20 subjects, girls had done extraordinarily well in English, Swahili, C.R.E, Home Science, Art and Design and Metal Works.
Unfortunately some 100 candidates will miss their results due to suspected malpractice.
Amina, however, said no one will be punished unfairly.
She said investigations have been launched and the report will be out before end of January 2019.
