Well done FreddyDaniel: I spent 2 weeks analyzing JAMB past questions from 2015-2025 (all 10 years) to find patterns.
Here's what I discovered: JAMB is NOT random.
The same topics appear EVERY SINGLE YEAR. If you master these, you can score 250+ even without covering the entire syllabus.
METHODOLOGY:
I went through 10 years × 180 questions = 1,800 questions total Categorized every question by topic Calculated frequency percentages
Here are the results:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
USE OF ENGLISH (60 questions)
HIGH-YIELD TOPICS (appears in 9-10 out of 10 years):
1. Comprehension Passages (20-25 questions ALWAYS) - Usually 3 passages: narrative, argumentative, expository - Strategy: Read questions FIRST, then scan passage for answers
2. Lexis and Structure (15-20 questions ALWAYS) - Synonyms/antonyms - Sentence completion - Common idioms - Study tip: Memorize high-frequency word lists
3. Oral English (10-15 questions ALWAYS) - Stress patterns - Vowel sounds - Consonant sounds - Most students skip this = FREE POINTS
4. Novel Questions (10 questions ALWAYS) - 2026 novel: "The Lekki Headmaster" - NOT OPTIONAL if you want 280+
MEDIUM-YIELD (5-8 out of 10 years): - Grammar/Tenses (5-8 questions) - Register/Technical terms (3-5 questions)
LOW-YIELD (less than 5 out of 10 years): - Figurative language (2-3 questions) - Sentence types (1-2 questions)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MATHEMATICS (40 questions)
HIGH-YIELD TOPICS (appear in 9-10 out of 10 years):
1. Algebra (5-7 questions ALWAYS) - Simplification, factorization, expansion - Master this = automatic 7 marks
2. Indices/Logarithms (4-6 questions ALWAYS) - Laws of indices - Logarithm rules
3. Percentages/Ratios (3-5 questions ALWAYS) - Word problems, profit/loss, simple/compound interest
4. Coordinate Geometry (3-4 questions ALWAYS) - Midpoint, distance, gradient, equation of line
5. Trigonometry (3-5 questions ALWAYS) - SOHCAHTOA, trig ratios, bearings
6. Mensuration (3-4 questions ALWAYS) - Area, perimeter, volume of shapes
7. Sequences (2-3 questions ALWAYS) - AP, GP, nth term
8. Statistics (2-3 questions ALWAYS) - Mean, median, mode, frequency tables
THESE 8 TOPICS = 28-32 questions out of 40!
MEDIUM-YIELD (5-8 out of 10 years): - Quadratics (2-3 questions) - Inequalities (2 questions) - Sets (1-2 questions)
LOW-YIELD (less than 5 out of 10 years): - Matrices (0-2 questions) - Vectors (0-1 questions) - Binary operations (0-1 questions)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PHYSICS (40 questions)
HIGH-YIELD TOPICS:
1. Mechanics (12-15 questions ALWAYS) - Motion, forces, work/energy/power, machines
2. Electricity (8-10 questions ALWAYS) - Ohm's law, circuits, power
3. Waves (4-6 questions ALWAYS) - Light, sound, wave properties
4. Modern Physics (3-4 questions ALWAYS) - Atomic structure, radioactivity
These 4 = 27-35 questions out of 40
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CHEMISTRY (40 questions)
HIGH-YIELD TOPICS:
1. Organic Chemistry (10-12 questions ALWAYS) - Hydrocarbons, functional groups
2. Chemical Reactions (8-10 questions ALWAYS) - Redox, acids/bases, salts
3. Periodic Table (5-7 questions ALWAYS) - Groups, trends, properties
4. Mole Concept/Stoichiometry (4-6 questions ALWAYS)
These 4 = 27-35 questions out of 40
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
BIOLOGY (40 questions)
HIGH-YIELD TOPICS:
1. Cell Biology (6-8 questions ALWAYS) - Cell structure, cell division, diffusion/osmosis
2. Genetics (5-7 questions ALWAYS) - Heredity, variation, evolution
3. Human Systems (8-10 questions ALWAYS) - Digestive, circulatory, respiratory, excretory
4. Ecology (4-6 questions ALWAYS) - Food chains, populations, adaptation
5. Plant Biology (4-6 questions ALWAYS) - Photosynthesis, plant structure
These 5 = 27-37 questions out of 40
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
THE STRATEGY:
If you have 8 weeks and limited time:
PRIORITY 1 (Weeks 1-4): Master ALL high-yield topics - This gets you to 220-250 baseline
PRIORITY 2 (Weeks 5-6): Add medium-yield topics - This pushes you to 260-280
PRIORITY 3 (Weeks 7- : Light review of low-yield + intensive CBT practice - This gets you 280-320
DON'T study syllabus linearly (Chapter 1, then 2, then 3...). That's inefficient.
Study by FREQUENCY (most common topics first).

Work smarter, not harder. Focus on what JAMB actually tests, not what your textbook covers.
