I rolled with the the best graduating students back then, because I was an average student at best, they carried me along and it helped me a lot because I wasn't energetic or healthy enough to chase every mark. Carry overs are demoralizing, I didn't get any till I came out, although some lecturers would make sure they become your nightmare
Goodluck with the exam results
I am yet to have any Co as well and hope it will remain that way, I had one in the First semester Nd1 result that was posted but fortunately for me when I checked my portal, it had been changed to D pass, and since then I have been more serious with studies especially during exam cos CO is stressful...
so now I hope to finish without any CO in my record!
