UDS is saying that you only need aggregate 24 or better. They are also saying that you must first meet the general requirements first then the Faculty requirement to get admission into BA econs.
So read the requirements carefully.
SSSCE/WASSCE Holders (for Degree Programmes)
SSSCE/WASSCE holders seeking admission into Degree programmes must have at least C6 (WASSCE candidates) or D (SSSCE candidates) in all their three Core and three Elective Subjects. WASSCE holders who have Grade D7 or E8 or F9 in any one of their three Core or three Elective subjects are advised not to apply for a degree programme. Also, SSSCE holders who have either Grade E or Grade F in any of their three Core or three Elective Subjects are advised not to apply for a degree programme.
Candidates should therefore possess, at least, credit scores/grades in the following:
Three core subjects (English Language, Mathematics (Core) and Integrated Science / Social Studies).
Any three elective subjects in the relevant programmes.
Aggregate Score of the best six subjects (three core and three electives) must not exceed 36 (for WASSCE scale) and 24 (for SSSCE scale). However, admissions will be on competitive basis, and various programmes offered in UDS have their cut-off points much lower than aggregate 36 for WASSCE (and 24 for SSSCE).
Candidates should note that Social Studies is not an elective subject.
For candidates who read Arts and Business subjects at SSSCE/WASSCE, a grade in Social Studies may be used in place of the grade in Integrated Science in the calculation of their aggregates if the Social Studies grade is better than the grade in Integrated Science. This is however on condition that the candidate has at least a pass in Integrated Science.
For Science students, however, Social Studies (Core) does not replace Integrated Science (Core) in the calculation of candidates’ aggregates.
In uds, the program is called DEED (DEPARTMENT OF ECONOMICS AND ENTREPRENEURSHIP DEVELOPMENT )
The department says they do not have any specific cut-off apart from aggregate 24 or better.
