Week 2

Fundamentals of double-entry bookkeeping & The trial balance and the accounting equation

  • Balance off 12 ledger accounts and bring down opening balances for the next period

  • Total each day book and transfer the totals to the general ledger

Your checkpoint

A completed set of day books for 20 transactions, with month-end column totals that tie back to the source documents listed alongside them.

Week 4

Business documents, coding and books of prime entry

  • Record receipts and payments in a two-column cash book and balance it off

  • Operate an imprest petty cash book, including a reimbursement that restores the float to its agreed amount

  • Write journal entries for three non-cash adjustments and post them to the general ledger

  • Distinguish errors that unbalance the trial balance from those that do not, listing at least six error types with an example of each

  • Correct 10 errors by journal entry and clear a suspense account to nil

  • Restate the accounting equation after the corrections to show the effect on capital

  • Explain how compensating errors can leave a trial balance in agreement despite being wrong

Your checkpoint

A 10-error correction exercise with a suspense account cleared to zero, plus a one-page table of error types classified as trial-balance-affecting or not.
