From what I've seen, it's generally 1-3 markers on just one of those properties. Main thing for year 11 though is to understand what they are and what they cause - you need it for year 12.
For 3u/4u the cutoffs were ~57/84,75/120 respectively.
Since the papers are going to be out of 70 and 100 marks instead, are the raw marks required likely to increase or decrease?
