Stop trying to learn everything
With 30 days left, you cannot re-learn three years of maths from scratch — and trying to will burn you out before the exam even starts.
Instead, pull up the last 5 years of past papers and count which topics show up every single year. Trig graphs, functions, calculus, and finance almost always carry the most marks. Start there.
The 30-day split
Days 1–10: Work through one full past paper every two days, marking it yourself with the memo. Note every topic you lost marks on — that list is now your syllabus.
Days 11–24: Drill only the topics on that list. Redo the exact questions you got wrong until you can do them without looking at the memo.
Days 25–30: Full past papers under real time pressure, no notes, no calculator hints. This trains your exam stamina, not just your knowledge.
Method marks first, elegance later
In the last month, stop worrying about the 'neatest' way to solve something. Markers award marks for correct method, not style — so lock in one reliable method per topic and use it every time, even under pressure.
