Suggested order

1. Study Guide (20–30 min)

Skim every module — formulas + plain-English breakdowns of the tricky bits (skewness, conditional probability, Binomial vs Poisson vs Normal).

2. Flashcards (20 min)

Drill definitions & formulas until "Know it" pile is full.

3. Quiz practice (30 min)

Answer with instant explanations. Filter by your weakest topic.

4. CBT Simulation (final run)

Timed, real exam‑style mixed paper. Simulates the actual CBT.

High‑yield formula sheet

Quick reference — full sheet under "Formulas" tab

Mean (grouped): X̄ = Σfx / Σf

Sample variance: s² = Σ(x−x̄)² / (n−1)

CV = (SD / Mean) × 100%

Skewness (Pearson): Sk = (Mean − Mode) / SD

Binomial: mean = np, var = npq

Poisson: mean = var = λ, CV = 100/√λ %

Normal: Z = (X − μ) / σ
