What does "post-secondary academic work" mean? While searching for PhD programs, I read a requirement that states I should send in my application an official transcript of all "post-secondary academic work completed to date". Surely this cannot mean all work, including published articles or lectures? 

My question is: What does "post-secondary academic work" mean?  Should I send academic work from both my completed Bachelor and from the Bachelor I did not complete? (BTW, is this expression correct, "completed Bachelor"? What would be a better English expression?)

Thank you!
In your question, you say they ask for the transcript of all work.  They don't want all work, as no one has that kind of time to read it all, they just want to know your performance in each course/module/etc.

The reason they stress the transcripts of all work, is that sometimes someone may have, as in your case, completed one program but not another and they would like to see the performance from that incomplete program (or perhaps you did two programs —in full— but one was in an unrelated field, they still want to see how you did in both).

Transcripts, thankfully, generally aren't very expensive to have translated.
