24 hours to exam? This page tells you exactly what to focus on, what to skip, and how to manage your time tomorrow.
CBSE Class 12 Economics
24 Hours Before the Exam
No time for everything. This guide tells you exactly what to revise, which topics almost certainly appear, what mistakes to avoid, and how to manage your 3 hours in the exam hall.
Focus on These Chapters First
- National Income aggregates — formulae connecting GDP, NDP, GNP, NNP, FC, MP
- Money Multiplier — formula (1/LRR), credit creation process
- Investment Multiplier — K = 1/(1−MPC) = 1/MPS, MPC + MPS = 1
- Demand and Supply analysis — equilibrium, shifts vs movements, elasticity formulae
- Government Budget — Revenue Deficit, Fiscal Deficit, Primary Deficit formulae
- Balance of Payments — current account vs capital account, exchange rate determination
- Price elasticity of demand — formula, types, determinants
- Keynesian income determination — deflationary and inflationary gap with diagrams
Key Formulas & Facts to Memorise Right Now
- GDP_MP = C + I + G + (X − M) | NDP = GDP − Depreciation | GNP = GDP + NFIA
- NNP_FC = GNP_MP − Depreciation − Net Indirect Taxes
- Money multiplier = 1/LRR | MPC + MPS = 1 | K = 1/MPS
- Price Elasticity of Demand = % change in Qty / % change in Price
- Revenue Deficit = Revenue Expenditure − Revenue Receipts
- Fiscal Deficit = Total Expenditure − Total Receipts (excluding borrowings)
- Primary Deficit = Fiscal Deficit − Interest Payments
- APC = C/Y | APS = S/Y | MPC = ΔC/ΔY | MPS = ΔS/ΔY
Timing Strategy for 3 hours Exam
- 1First 15 min: Read paper — identify all numericals and diagram-based questions
- 20–30 min: All MCQs — Economics MCQs are formula or definition based, quick
- 330–80 min: 3 and 4-mark questions — definitions, distinctions, short analysis
- 480–150 min: 6-mark questions — full explanations with diagrams where applicable
- 5150–170 min: Case study — apply macroeconomic concepts to the given scenario
- 6Last 10 min: Verify all numerical calculations and formula usage
Common Mistakes — Avoid These Tomorrow
- ✕Confusing GNP with GDP — GNP adds NFIA (Net Factor Income from Abroad)
- ✕Using wrong Fiscal Deficit formula — Total Expenditure minus receipts EXCLUDING borrowings
- ✕Confusing Primary Deficit and Revenue Deficit — they measure different things
- ✕Writing K = 1/MPC for multiplier — it is K = 1/MPS
- ✕Confusing movement along demand curve (own price) with shift (other factors change)
- ✕Skipping formula before numericals — examiners deduct marks for missing formula
Must Attempt — Never Leave These Blank
- ✓All national income aggregates numericals — direct formula substitution
- ✓Money multiplier and investment multiplier problems — formulae are fixed
- ✓Diagram questions — even a rough correct diagram earns diagram marks
- ✓All MCQs — Economics MCQs are entirely memory/formula based, never leave blank
Skip If Unsure (Return If Time Permits)
- →Complex open economy questions if unfamiliar — do domestic macro topics first
- →Long theory questions you haven't revised — attempt known topics first
Remember: Partial marks exist. Attempt and leave if stuck — come back if time allows. Never spend more than 8 minutes on a single 5-mark question.
Economics has a perfect balance of theory and numericals. Know the key formulae and draw demand/supply diagrams clearly — you can score 70% without memorising every line of the textbook.
Night Before — Non-Academic Checklist
Pack your bag
Admit card, 2 pens, pencil, eraser, ruler, geometry box (if needed)
Sleep by 10 PM
Your brain consolidates memory during sleep. Late-night cramming hurts more than it helps
Stop studying at 9 PM
Whatever you don't know by tonight won't be learnt in an hour. Trust your preparation
Set two alarms
One to wake up, one as a backup. Arrive at the centre 30 minutes before the exam
