IBSL Intermediate in Applied Banking and Finance (IABF) Exam common mistakes

IBSL Intermediate in Applied Banking and Finance (IABF) Exam · Understand the traps and how to avoid them.

Mistake 1

Calculating simple interest when the question specifies compound interest (or compounding at a frequency other than annual), producing an answer that is arithmetically tidy but wrong.

Under time pressure candidates default to the simplest formula they memorised and skip the compounding instruction embedded in the stem, especially when the rate is given as an annual figure.

What to do instead

Before computing, underline the rate basis and any compounding frequency in the stem, then write the formula down first (e.g. A = P(1 + r/n)^(nt)) and substitute only after the formula is on the page.

Mistake 2

Confusing debit and credit entries when recording a transaction, for example crediting an asset account to increase it or debiting a liability to reduce it.

Candidates learn double-entry as a list of rules rather than as an effect on the accounting equation, so under exam pressure they guess the side rather than deriving it.

What to do instead

For every entry, state the effect on assets, liabilities and equity first, then apply the rule that increases in assets and expenses are debits; practise by writing the accounting equation beside each journal.

Mistake 3

Answering a 'which is NOT' or 'least likely' question by selecting the first true statement encountered.

The brain latches onto a statement it recognises as correct and stops reading, so the negative qualifier in the stem is overlooked.

What to do instead

Circle or highlight the negative qualifier in the stem before reading the options, and evaluate each option as true or false before choosing the one that does not fit.

Mistake 4

Computing a ratio or margin using the wrong denominator, such as dividing by total assets when the question asks for a return on equity or dividing by sales when it asks for a margin on cost.

Standard ratios are memorised by name only, and several share the same numerator, so candidates pick whichever denominator feels familiar.

What to do instead

Before calculating, write the ratio in words (e.g. 'profit divided by equity') rather than by acronym, and confirm the denominator matches the words in the stem.

Mistake 5

Mixing up the direction of a foreign exchange quote and applying the wrong rate, for example multiplying by the rate when division is required to convert into the base currency.

Quotation conventions (base versus counter currency) are abstract, and candidates do not check which currency the answer must be expressed in.

What to do instead

Write the required output currency at the top of the working, then set up the conversion as a unit-cancellation chain so the unwanted currency appears in the denominator and cancels.

Mistake 6

Describing a concept in general terms without using the technical terminology the mark scheme rewards, such as saying 'the bank checks the borrower can pay it back' instead of 'credit assessment of capacity to service debt from verified income'.

Candidates fear using a term incorrectly, so they hedge with plain language; in constructed-response questions this forfeits the marks allocated to precise terminology.

What to do instead

Build a one-page glossary per topic and rehearse each definition aloud in the exam register; in practice answers, deliberately insert the technical term and then explain it in one clause.

Mistake 7

Listing points without applying them to the scenario given in the stem, so a case-based question about a small exporter is answered with generic text about 'businesses'.

Candidates reproduce memorised notes because it feels safer than engaging with the specifics of the case, and they run out of time to tailor the answer.

What to do instead

Before writing, extract the three or four facts that distinguish the case (size, sector, currency exposure, tenor) and explicitly link each point to one of those facts in the same sentence.

Mistake 8

Confusing the roles of the central bank, a commercial bank and a regulator when answering questions on monetary policy, prudential supervision or lender-of-last-resort functions.

These institutions overlap in practice, and revision notes often describe functions without clearly attributing each to its body, so the boundaries blur.

What to do instead

Draw a three-column table (central bank, commercial bank, regulator) and place each function in exactly one column; test yourself by naming the institution before naming the function.

Mistake 9

Ignoring the marks available and writing an essay-length answer to a four-mark question while leaving a twelve-mark question half-finished.

Candidates answer in the order questions appear and write until they feel finished, without allocating time in proportion to marks.

What to do instead

In the first two minutes, write the mark value beside each question and convert it to minutes (roughly one minute per mark plus reading time); move on when the allocated time for a question expires.

Mistake 10

Quoting a figure or a regulatory threshold from memory without showing the calculation or stating the assumption behind it.

Candidates believe the final number is what earns marks, so they omit the working, and an error in the figure then loses both the method and the answer marks.

What to do instead

Always show the formula, the substitution and the result on separate lines, and state any assumption (for example the day-count convention) explicitly so method marks survive an arithmetic slip.
