The access course are for people who did not meet the requirements .
The polytechnics need only two elective subjects and 3 core subjects for application.
Im sure your friends did not fail all their elective subjects.
if your friends did not write any electives during the entrance exams, that means that they failed only two electives in WASSCE and therefore they do not have to write any exams since they can use the other two that they passed to apply.
Please do you get it now?
let me know if you still dont get it and i will explain further.
