Speaking exclusively to Kenyans.co.ke, 13-year-old Mwea revealed that she intends to pursue a career in Pharmacy after her secondary school education.
"I did not believe it but the moment our headteacher confirmed it, I realised I was the top candidate. I thank my teachers, it is out of reading and God's blessings that this happened.
"I would love to join Kenya High, Kianda High or Brook House school," stated the joyous Olive who sat her exams at Riara Group of Schools in Nairobi.
Mwea indicated that she had hoped to score 433 marks terming the news of her exemplary performance as "unbelievable and exciting".
On the other hand, Odhiambo sat his KCPE exams at Kakamega Hills Academy.
Joseph Kamau, a teacher at Riara Group of Schools noted that the school's good performance was as a result of the good relationship between teachers and parents.
