I missed only 2 tutes and was late to 1 (I don't know how this was marked late, I walked in literally 15 mins late and I've heard people walk in an hour late and nothing happens), out of the 11.
Also 17/20 on lecture attendance.
Assuming I get like a 47-49, what are my chances of being bumped up if the examiner or whoever marks the unit considers bumping people up?
There's no way of predicting it, sorry. You'll just have to wait and see.
What happens in most cases is that the student has failed the final exam by a small margin and therefore has failed a hurdle requirement and has a maximum final mark of 48. However, if it's a case where the student would've passed the unit overall had it not been for the final exam hurdle requirement, then the unit coordinator might bump up your final exam mark to a 50, so you get an overall passing grade.
Example:In-Semester Assessment: Worth 70%, scored 80/100
Exam: Worth 30%, scored 49/100
Final Mark: 70 x (80/100) + 30 x (49/100) = 70.7
BUT because of the failed hurdle requirement, the final mark is reduced to 48.
It's in this sort of circumstance that the unit coordinator may review your final exam alongside your tute attendance and in-semester assessment to decide whether to award you that extra point on your final exam paper so you pass the hurdle and therefore the unit.
On the other hand, if you've failed the unit irrespective of hurdle requirements (both your in-semester and final exam marks weren't good enough), then you've very unlikely to be bumped up. Unit coordinators try to pass people who demonstrate appropriate knowledge and understanding of the unit. They're not evil, so they really want to pass people whom they think have the knowledge but just froze during the exam. Conversely, they're unlikely to pass someone whom hasn't done well during semester because they probably don't have appropriate knowledge and their fail mark wasn't just a matter of them going blank during the exam.
Aside from this, there are some other factors that influence a unit coordinator. One important factor is grade distribution. Unit coordinators have to justify themselves to the university if too many students fail a unit, because for >15% of students to fail is rare and it's likely to be the unit coordinator's fault. Therefore, sometimes a unit coordinator is inclined to scale ALL students' exam score up a few points if the exam can be considered too hard and too many students would fail without the scaling.
Lastly, there's a degree of discretion exercised by the unit coordinator. They simply choose whether or not to review and bump up scores; it's up to them to decide.
