not applicable in Nigeria anymore.

Take a look at the time table in the attachment
It divided into sections such as management, sciences
and art, it depends your area in academics
it still available, nabteb has A' level, one thing
is that you have just 3subjects to specialize, which will have
sub subject in any course you want to study
If you want to study medicine for example, @ the
end of yours study, you be graded on bio,chem, phy
It nine month programme, but expensive.
