ExamPadi Editorial · Updated · 6 min read
Commerce looks simple until the exam. Then you meet several types of business, different bank accounts, a string of trade documents and definitions that look alike. Students who study it as a list of unrelated facts struggle. Students who study it as a connected system, with goods moving from producer to consumer and money, documents and services supporting each step, find it manageable.
See the whole picture first
Commerce is the study of everything that helps goods and services reach the people who want them. Start your revision by drawing a simple chain:
Producer → Wholesaler → Retailer → Consumer
Now add the aids to trade that support this chain:
| Aid | What it does | Example |
|---|---|---|
| Transport | Moves goods | Road, rail, air, water |
| Warehousing | Stores goods | Warehouse, cold room |
| Banking | Holds and moves money | Current and savings accounts, loans |
| Insurance | Protects against loss | Fire, goods in transit, motor |
| Advertising | Informs buyers | Radio, billboards, social media |
| Communication | Sends information | Phone, email, post |
The ExamPadi topic list includes trade, aids to trade, banking, insurance, the stock exchange, marketing, business organisations, accounts, public enterprises and money. Almost everything fits somewhere on this picture.
Compare, do not list
Many Commerce questions ask you to define, state features, give advantages and disadvantages or distinguish between two things. Comparison tables are your best tool. Below is an original table you can adapt for revision.
| Feature | Sole proprietorship | Partnership | Private limited company |
|---|---|---|---|
| Owners | One person | Two or more people | Shareholders |
| Capital | Owner's savings and loans | Contributions of partners | Sale of shares to a limited group |
| Liability | Owner is personally liable | Generally personally liable | Limited to shares held |
| Decisions | Owner decides | Partners agree | Directors manage |
Check the details against your textbook and the current syllabus, since legal descriptions differ slightly between sources. Then make similar tables for:
- retail and wholesale trade,
- home trade and foreign trade,
- current, savings and fixed deposit accounts,
- commercial banks and the central bank,
- insurance principles,
- public and private enterprises.
Trade documents: follow the transaction
Documents are a favourite for objective questions. Put them in the order they appear in a real purchase:
- Enquiry (buyer asks about goods and price)
- Quotation or catalogue (seller replies)
- Order (buyer confirms what they want)
- Invoice (seller bills the buyer)
- Delivery note (accompanies the goods)
- Receipt (proof of payment)
- Credit note or debit note (adjustments for returns or errors)
For foreign trade, add documents such as the bill of lading and the certificate of origin. Learn who prepares each one and what it proves.
Banking, money and the stock exchange
For banking, know the functions of commercial banks (accepting deposits, giving loans, offering payments services) and the central bank (issuing currency, acting as banker to the government and other banks, and implementing monetary policy). Understand the difference between a cheque, a draft and an electronic transfer.
For money, know its functions (medium of exchange, store of value, unit of account, standard of deferred payment) and the qualities good money should have, such as acceptability, durability and portability.
For the stock exchange, know what it is, what a share and a bond are, and the difference between the primary and secondary markets.
Simple calculations
Here is an original example.
A trader buys goods for ₦8,000 and sells them for ₦10,000. Find the profit and the percentage profit on cost.
- Profit = 10,000 − 8,000 = ₦2,000
- Percentage profit on cost = 2,000 / 8,000 × 100 = 25%
Practise a few of these each week: profit and loss, trade discount, cash discount, mark-up and margin. Show your steps.
Marketing and business organisation
Learn the marketing mix in plain terms: product, price, place and promotion. For each, write one question a business owner would ask. For example, for price: "How much will customers pay, and does it cover our cost?" For business organisations, learn the typical sectors and ownership types, and how public enterprises differ from private ones in objectives and funding.

Mistakes to avoid
- Defining a term using the same word ("A wholesaler is someone who wholesales").
- Giving only advantages when the question asks for advantages and disadvantages.
- Leaving out units or the naira sign in calculations.
- Searching for "expo". It is not study, it is a risk, and the real marks come from understanding.

Is Commerce easier than Economics?
They are different. Commerce is about how business and trade work in practice, and it uses more descriptive content. Economics uses more theory and diagrams. Many students find Commerce more concrete, but it still needs careful learning.
Which Commerce topics are the easiest to mix up?
Types of business organisation, types of bank and account, and the documents used in trade, because many terms look alike. Use comparison tables to separate them.
Do I need to know calculations?
There are some simple calculations, such as profit and loss, mark-up and margin, and discounts. They are usually short, so practise them regularly.
How is Commerce linked to Accounting?
Commerce explains the business world; Accounting records and reports its transactions. Studying them together can help you understand both.
