What you will submit

A written numbers file, in your own words, containing: the situation and where the figures came from; the starting figures in naira; at least four fully worked calculations covering percentage or margin, ratio or proportion, an equation you formed and solved and checked, and break-even or interest; a decision statement after each calculation; your checking section; and a closing list of what changed and the one number you will track monthly.

What to do, step by step

  1. Choose one real situation you genuinely know: a small business (yours or one you help with), your household budget, or a building or materials job you are planning. Write one short paragraph describing it and where your figures come from — your own records, a market survey you did, or written quotes. If you are using someone else's business or household, change the names and leave out anything personal such as account numbers, addresses or phone numbers.
  2. List your starting figures in naira before you calculate anything: prices, costs, quantities, measurements, rates and dates as they actually are. Say which figures are measured, which are quoted by someone else, and which are your own estimate — a grader must be able to see where every number entered your work.
  3. Apply at least four techniques from the course and show every step in writing, not just the final answer. You must include (a) a percentage calculation that is either a margin or markup decision, or a VAT or commission calculation; (b) a ratio or proportion calculation, such as sharing, scaling, mixing or a unit-price comparison; (c) an equation you formed yourself from a word problem, solved step by step, with the answer substituted back to check it; and (d) either a break-even calculation or an interest calculation. Add measurement and quantity estimating as a fifth if your situation is a building or materials job.
  4. After each calculation, write one or two sentences naming the decision that number supports — for example what price you will now charge, how many units you must sell, which supplier or pack size you will buy, which loan you will refuse, or how many cartons of tiles you will order. A number with no decision attached does not count toward the requirement.
  5. Check your own work and say so. Re-add every total a second way, substitute your equation answer back into the original equation, and state one figure you are unsure about and how you would confirm it — a supplier, an official source, or your own measurement.
  6. Finish with a short section listing the two or three things this exercise changed in what you were going to do, and one number you now intend to track every month.

How it is graded

CriterionWeight
Real, sourced starting figures in naira are listed before any calculation, with each figure labelled as measured, quoted or estimated15%
At least four required techniques appear (percentage/margin or VAT/commission; ratio or proportion; a self-formed equation; break-even or interest), each shown step by step rather than as a bare answer30%
The arithmetic is correct throughout and every total or answer is verified — sums re-added a second way, and the equation answer substituted back into the original equation25%
Each calculation is followed by a stated decision naming the specific action it supports (a price, a quantity, a supplier, an order size, a loan refused)20%
The submission names at least one figure the learner is unsure about with a specific way to confirm it, and closes with what changed plus one number to track monthly10%

You need 65% overall to pass. A failed submission comes back with feedback and can be revised and resubmitted.

Before you submit: make your link public

If your work lives in Google Drive or Google Docs, open Share → General access and change “Restricted” to “Anyone with the link” (Viewer). Then paste the link into a private browser window: if it opens without sign-in, you are ready. A private link cannot be graded — it is the single most common reason a good project fails.

Frequently asked questions

Do I have to finish Practical Mathematics for Nigerian Life and Business before submitting the project?

Yes. The submission screen opens once every lesson in Practical Mathematics for Nigerian Life and Business is marked complete. The lessons are where the methods, the Nigerian context and the worked examples the project depends on are taught.

How is the project graded?

An examiner scores each rubric criterion from 0 to 100 and weights them as shown on this page; you need 65% overall to pass. Most submissions are graded within minutes and you get written feedback on what was strong and what to improve.

Can I resubmit if I fail?

Yes. A failed project comes back with feedback; revise the weak parts and resubmit. A passed project is final — the certificate is issued and cannot be re-rolled.

What do I actually submit?

A write-up of what you did (under 5,000 characters). You can mention a public link to supporting files in the write-up. The free project workbook on this page walks you through all 6 steps.

Is the certificate real?

Yes. Passing this project issues a certificate with a unique verification code. Anyone — an employer, a client, a school — can open the verification page and see that the certificate is genuine and which project earned it.
