Everything here is built from the FBA 120 course module (3 modules, 26 study sessions: differentiation, integration, vectors, matrices, sequences & series, mathematics of finance, probability, permutations & combinations), the 200-level DLI FBA 120 past-question bank (every answer re-worked — wrong keys in the document are corrected and flagged ⚠) and the FBA 120 CBT quiz (answers worked out step by step). Work top to bottom, or jump straight to the CBT if you're short on time.
Work through all 26 sessions — rules, worked examples and the exact business applications (MC, MR, AC, profit, elasticity, compound interest, annuities, probability) the CBT loves.
2. Flashcards (20 min)Drill every formula and definition until your "Know it" pile is full.
3. Quiz practice (30 min)Instant working after every answer. Filter by your weakest topic.
4. CBT Simulation (final run)Timed, mixed, exam-style paper. Keep scrap paper and a calculator handy.

The 200-level DLI FBA 120 past-question bank — differentiation applications, probability, integration, sequences & series, permutations & combinations and commercial maths — with full working. The original document's answer key had many errors; every question was re-solved, and where the key or options were wrong you'll see ⚠ Corrected with the reason. Tap a question to see the answer.
