I'm a Repeat Student
Students repeating part or all of the previous academic year can be an Internal Repeat or an External Repeat.
Internal Repeat students are those who have failed certain components from their previous year’s study and are required to return to DIT to attend classes and repeat those components. Components can include examinations, continuous assessments, assignments or laboratory work. In some instances students do not have the option to repeat externally as attendance is mandatory. As an internal repeat you register and pay fees following which you are entitled to retain your student ID card, attend classes, sit examinations and avail of all DIT’s student facilities. -
