Spanish to English Other Education / Pedagogy Venezuelan university transcript

Good evening! I have some abbreviations/initials that I'd like help with.

The only context is the explanation of the initials, referring to initials used in an academic transcript:

A.A. ASIGNATURA NOTA OB.
[followed by the list of subjects]

Table of Initials in the OB. column (I'm translating "OB" as "Observations")

AP: Aplazado
DF: DIFERIDO DE FINAL
EP: Excluido por Promedio
EI: Excluido por Inasistencia

At first, I translated it as "DEFERRED FINAL". But, there's another phrase in the second column, "FINAL DE ARRASTRE", which seems to be a better translation of "deferred final".

As always, a thousand thanks!
