Who would imagine the digital era would bring all these possibilities to the world.
When I was in high we had organised into study groups the best student in class teamed with the worst and so on. This strategy ended giving our class the best we could. ALl the students in my class qualified for university, I still associate the excellent work we did with the idea of teaming up and helping each other this was way back in 94, and if you want to know where I went to high is 'Materi girls' in a small remote area in Tharaka, Meru Kenya.
