Do not wait until the end of a question to use your GC. Use it to find intersection points, evaluate definite integrals, and verify matrix inverses immediately. This ensures your analytical working matches the numerical reality.

A defining feature of the 2012 paper was its relentless attack on conceptual fragility. One notable example was a question on the relationship between the roots of a polynomial and its coefficients. While a standard question might ask students to find the sum and product of roots, the NJC paper presented a cubic with an unknown parameter and asked for the condition under which the roots formed a geometric progression. This required students to move beyond the mechanical use of formulas (sum of roots = -b/a) to a deep understanding of how root relationships interlink. Students who memorised formulae without understanding the underlying algebra—that the roots are an arithmetic or geometric sequence—invariably faltered. This approach rewarded genuine insight rather than algorithmic repetition.
