Thanks a lot for sharing such a useful information but still my query is not clear completely.
Here I am explaining in detail:
Suppose, I got fail in three subjects through out my studies
Lets consider,
1. Subject A
2. Subject B
3. Subject C
Now, I have reattempted
subject A - 3 times
subject B - 2 times
subject C - 2 times.
So now my query is colleges in canada are consider backlogs per subject which is 3 backlogs ( Subject A, Subject B, subject C ) or total reattempts of all subjects which is 3 times+2times+2times = 7 backlogs ?
Please help me out, I am very confused.
