BCS Written Finance common mistakes
BCS Written Finance · Understand the traps and how to avoid them.
Writing a general essay on 'financial discipline' in the essay paper without anchoring it in Bangladesh's legal and institutional framework (Constitution, PFM Act, budget cycle), so the answer never demonstrates technical command of public financial management.
Candidates prepare from newspaper editorials and memorised current-affairs notes because those are easier to revise than statutes and circulars, and the essay format tempts them into rhetorical generalities rather than precise institutional analysis.
What to do instead
For every public-finance essay, build a fixed skeleton: legal basis, institutional actors, budget-cycle stage, a concrete figure or mechanism, and a recommendation. Practise writing three essays a week where at least half the paragraphs name a specific law, rule, or process step.
Presenting a budget or variance analysis as a narrative list of numbers without computing ratios, percentages, or year-on-year changes, so the examiner cannot see any analytical work.
Candidates treat the question as recall of figures rather than analysis, and many have weak arithmetic confidence under time pressure, so they avoid computation and pad with description.
What to do instead
Adopt a habit of converting every figure into at least one derived measure (percentage of total, growth rate, variance as a share of budget, ratio to revenue). Do timed drills where raw tables must be turned into three computed observations within five minutes.
Applying double-entry logic incorrectly in journal-entry questions, for example debiting an increase in a liability or crediting an expense when recording a payment, producing balanced but conceptually wrong entries.
Candidates memorise entry templates for common transactions but never internalise the accounting equation and the normal balance of each account class, so novel transactions defeat the template.
What to do instead
Before writing any entry, state the affected accounts, their class, and the direction of change aloud. Rebuild the trial balance from the equation after each practice set, and drill mixed transactions (accruals, prepayments, depreciation, provisions) rather than repeated single-type examples.
Confusing the distinct roles of internal control, internal audit, and external audit in governance questions, describing them as interchangeable layers of 'checking' without separating management's responsibility from independent assurance.
The three concepts are taught together and share vocabulary, so candidates blur ownership of the control system, the monitoring function, and the independent opinion, and they lose the marks allocated to role differentiation.
What to do instead
Maintain a one-page comparison table (who owns it, who performs it, to whom it reports, what it produces, its limits) and answer every governance question by explicitly assigning each role before discussing weaknesses and recommendations.
Computing project appraisal metrics without a coherent treatment of incremental cash flows, mixing financing costs into operating cash flow, ignoring working capital and salvage value, or discounting nominal flows at a real rate.
Candidates learn the NPV and IRR formulas mechanically and skip the cash-flow construction stage, and textbook examples often omit the complications that exam scenarios deliberately include.
What to do instead
Always lay out a cash-flow schedule in four blocks (initial outlay, operating flows, working capital changes, terminal flows) before discounting, and check rate-flow consistency explicitly. Practise one full-length appraisal per study session rather than isolated formula plugging.
Describing monetary policy transmission and financial-sector regulation in generic terms without naming the instruments, the responsible institutions, or the specific prudential tools, so answers could apply to any country.
Candidates rely on introductory economics summaries and shy away from institutional detail, fearing factual error, but the omission itself costs most of the marks.
What to do instead
Build an instrument-and-institution map (policy tools, prudential ratios, supervisory bodies, market segments) and rehearse answers that attach each instrument to its operator and its intended effect. Verify facts against official publications before committing them to notes.
Answering fiscal-policy questions with only demand-side assertions, omitting the revenue versus expenditure composition of the deficit, its financing sources, and the resulting debt and crowding-out implications.
Candidates treat 'fiscal deficit' as a single number and have not practised decomposing it, so they cannot distinguish a tax-cut deficit from a capital-spending deficit in their analysis.
What to do instead
For every fiscal question, write the identity explicitly (revenue, expenditure, deficit, financing) and then analyse composition and financing separately. Prepare two contrasting scenarios so the analytical distinction becomes automatic.
Discussing ICT in finance as a list of technologies (blockchain, mobile money, AI) with no governance architecture, no control implications, and no link to the specific function asked about.
Technology topics invite buzzword enumeration, and candidates lack frameworks for IT governance, data integrity, and control, so they substitute novelty for analysis.
What to do instead
Answer ICT questions through a fixed lens: the process being supported, the data and control risks introduced, the governance and assurance response, and the capacity constraints. Anchor each technology to a named function such as budget execution, treasury, audit analytics, or payment settlement.
Running out of time because the paper is attempted in the given order with equal effort per question, leaving high-weight compulsory sections or the final essay underdeveloped or blank.
Candidates rehearse content but never rehearse the exam as a time-allocation problem, and anxiety leads them to over-invest in the first question they can answer well.
What to do instead
Sit at least four full mock papers under strict timing, pre-assign minutes per question and per mark before starting, and practise abandoning an overlong answer at the planned minute. Review the time log afterwards to identify where overruns occur.
Quoting statistics, legal provisions, or institutional facts from memory that are outdated, misattributed, or invented, and presenting them without hedging or source.
Candidates believe a confident figure earns marks and fear that admitting uncertainty looks weak, so they fabricate precision rather than reason from principles.
What to do instead
Use a two-tier note system separating verified facts (with source and date) from principles and reasoning. In the exam, where a precise figure is uncertain, state the mechanism and direction of the effect instead, and reserve specific numbers for facts you have verified.
