NJC loved tying DEs to real-world scenarios, specifically a leaking tank with a variable cross-sectional area. The 2012 paper presented a diagram of a conical tank. : Seating arrangements and conditional probability
The Binomial question included a conditional probability clause ($P(X=k | X > m)$). Many students forget to recalculate the denominator (the sample space) when dealing with conditional probability, leading to lost marks. Struggle through it
Paper 2 of the 2012 NJC Prelim is where the school earned its reputation for "killer" application questions.
