How WAEC marks this
Examiners award method marks (M1) for stating the formula/definition and accuracy marks (A1) ONLY when SI units are written.
Watch out for
Writing bare numbers without working or omitting SI units loses up to 50% of Paper 2 marks even when the final value is right.

Overview — Agricultural Extension Services
How new agricultural knowledge and techniques reach farmers. This lesson is at the advanced level — by the end, you'll be able to recognise this question type, apply a reliable method, and avoid the traps that cost marks.
Key Concept
Agricultural extension services connect research institutions to farmers, using extension agents to demonstrate improved farming techniques, new crop varieties, and better management practices directly to farming communities, bridging the gap between agricultural research and everyday farm practice.
Why It's Tested This Way
WAEC/JAMB test agricultural extension because it explains HOW research-based agricultural improvements (developed by scientists) actually reach and change the practices of farmers, who may otherwise continue with traditional methods regardless of available improvements.
Method
When answering, be ready to explain the specific role of an extension agent (demonstrating, training, communicating between research and farmers) rather than describing extension services as simply 'helping farmers' in a vague sense.
Worked Example
Worked example: An extension agent demonstrating a new, higher-yielding maize variety on a small demonstration plot within a farming community allows local farmers to see the variety's real performance under their own local conditions before deciding to adopt it themselves.
Second Worked Example
Second worked example: Extension agents training farmers in improved storage techniques to reduce post-harvest losses (such as proper drying and pest-proof storage for grain) directly addresses a common practical problem that research alone, without an extension link to farmers, would not solve.
Common Traps
Common trap: assuming agricultural research automatically benefits farmers without a further step — WAEC specifically tests extension services as the necessary bridging mechanism between research findings and actual changes in farmer practice.
