How many marks can be dropped to still get a 45+?

[throwaway2016]

Just had my first bio sac. Made a couple of stupid errors and ended up with 23.5/25. This was the first of 3 experimental sacs out of 25 worth 50 marks for unit 3.

How many marks can I drop in my coursework to still be able to get above 45?

Hey! Ranking is far more important than actual marks in terms of achieving a high SS (Study Score). For all we know, your school's sacs could be ridiculously easy/hard, so eventually, the marks you achieve will me changed (moderated) either higher or lower. Focus on being towards the top of your class, and getting a mid-high A+ on the exam (i think this is between 104-107/110 marks)
