But still; I do agree with @MaichBlack; it takes too long to get a PhD in Kenya. The culprit, in my view is LAZINESS!
The students are lazy, but the supervisors are even lazier!
I know several Kenyan guys who went to UK universities for PhDs and spent over 6 years there doing little more than downing pints at the pubs. Eventually their scholarships were withdrawn and they returned to Kenya empty handed....
I also know several Kenyan supervisors who spend three months reading a 10-page chapter... claiming they are very busy with other research... for which they have no results to show!
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
