"KR Only" = registration for KR, and neither DL nor NMR.
"KR Joint" = registration for KR, and at least one of DL and NMR.
Similar for DL and NMR.
Registration for KR tutorials is included in the registration for any one of KR, DL or NMR.
SADC stands for Southern African Development Community.
So, any one who comes from one of the SADC countries will pay the same as a student.
If you donít know if you come from a SADC country, you probably donít :)
