KASNEB CS21 common mistakes

KASNEB CS21 · Understand the traps and how to avoid them.

Mistake 1

Preparing only the statement of profit or loss and statement of financial position while omitting the statement of cash flows or statement of changes in equity in a full financial-statements question.

Candidates memorise the two 'headline' statements and treat the supporting statements as optional, or run out of time after balancing the trial balance and drafting the main statements.

What to do instead

Before writing, list every statement the question requires and tick each off as completed; practise full-set drafting under timed conditions so the cash flow and equity statements become routine rather than an afterthought.

Mistake 2

Failing to adjust opening balances and prior-year figures for items such as accrued income, prepaid expenses, depreciation, or opening inventory before computing the current period result.

Candidates apply the matching concept only to obvious accruals and forget that opening balances already carry prior adjustments, leading to double counting or omission.

What to do instead

Work through a fixed checklist of year-end adjustments (accruals, prepayments, depreciation, inventory, bad debts, provisions) and reconcile each opening balance to the prior closing figure before posting current entries.

Mistake 3

Calculating NPV, IRR, payback or WACC using inconsistent cash flow conventions, for example discounting accounting profit instead of cash flow, or mixing pre-tax cash flows with an after-tax discount rate.

Candidates conflate profit and cash, and treat the discount rate as a plug-in number without checking whether it is nominal or real, pre- or post-tax.

What to do instead

Always build a cash-flow schedule first (incremental, after-tax, including working capital and terminal value), then state explicitly which discount rate basis is used and match it to the cash flows before computing the metric.

Mistake 4

Computing ratios or valuation figures with the wrong denominator or period, such as using closing rather than average receivables for receivable days, or annualising a half-year figure incorrectly.

Candidates memorise ratio formulas loosely and do not check whether the question supplies opening and closing balances or a part-year period.

What to do instead

Write the formula with its components before substituting numbers, and explicitly note whether average or closing balances and annual or part-year figures are being used; convert part-year data to an annual basis where the ratio requires it.

Mistake 5

Assessing creditworthiness using only one or two factors, such as the current ratio or a credit score, without integrating the five Cs or a structured framework.

Candidates default to the single most familiar metric under time pressure and do not practise applying a full credit assessment structure to a scenario.

What to do instead

Adopt a fixed template (character, capacity, capital, collateral, conditions, plus quantitative ratios and industry context) and answer every credit question against all elements of that template.

Mistake 6

Ignoring the distinction between a credit policy recommendation and its implementation, for example recommending tighter credit terms without addressing monitoring, collection procedures, or the cost-benefit trade-off.

Candidates treat credit questions as definition recall and do not connect policy design to its operational and financial consequences.

What to do instead

For every credit recommendation, state the expected effect on sales, bad debts, financing cost of receivables, and the control or monitoring mechanism required to enforce it.

Mistake 7

Describing corporate governance principles in the abstract without applying them to the specific parties, board structures, or conflicts described in the scenario.

Candidates revise governance as a list of codes and principles to recite, rather than as an analytical framework for identifying who is accountable to whom.

What to do instead

Practise mapping each principle (board independence, audit committee, disclosure, stakeholder accountability, risk oversight) onto the named actors in the scenario and stating the specific failure or remedy for each.

Mistake 8

Answering management questions with generic textbook definitions of leadership or motivation theories without diagnosing the situation or recommending a course of action.

Candidates learn theories as isolated content and are not trained to select and apply the relevant model to the facts given.

What to do instead

Structure answers as diagnosis, theory applied, and recommendation; name the model, show how its variables appear in the scenario, and conclude with a concrete action rather than a summary of the theory.

Mistake 9

Treating information systems controls as a list to memorise, so answers describe general controls without linking them to the specific risk, data flow, or control objective in the scenario.

Candidates revise IT controls and audit trails as definitions and do not practise identifying where in a described process a control gap actually sits.

What to do instead

For each IT question, trace the described process step by step, identify the specific risk at each step, and name the preventive or detective control that addresses it, including who performs it and how it is evidenced.

Mistake 10

Ignoring the interaction between business law, ethics, and the other domains, for example answering a question on directors' duties or professional ethics purely in accounting terms without citing the legal or regulatory obligation.

Candidates study each syllabus area in isolation and do not practise integrated questions that span disciplines.

What to do instead

When a question crosses domains, explicitly state the legal or regulatory source of the obligation, the ethical principle engaged, and the accounting or financial consequence, so the answer addresses all dimensions the examiner is testing.
