What has been postponed
The notice covers one group: remedial programme students newly placed at Debark University by the Ministry of Education for 2019 E.C. Their registration had been announced for Meskerem 28 and 29, 2019 E.C. The university gives the reason as the Ministry not yet having sent the information on the students it placed for the remedial programme, and says registration is postponed for an undetermined time.
No new date is given. Debark says it will announce one in a separate notice, so check its own channels before you set out.
What the notice does not say
The notice names remedial students only. It says nothing about Debark's other groups, so their dates are as Debark announced them earlier. Our roll-up of 2019 E.C. registration dates lists the university's first-year entrants and 2018 E.C. remedial passers together on Meskerem 28 and 29; for newly placed remedial students that row is now out of date. The roll-up is in University registration dates for 2019 E.C..
