The MS Office bank is small, at just over 120 published questions, and very specific. It exists because clerical posts such as UDC, LDC and Assistant include a computer-proficiency component in their written tests, and those questions are almost entirely about Microsoft Word and Excel. Word takes the larger share: the interface (ribbon, tabs, status bar), formatting, mail merge and the keyboard shortcuts for common actions. Excel questions focus on number formatting, cell references and basic functions.
A small number of PowerPoint questions round it out. The keyboard-shortcut questions repeat across papers with very little variation, so learning the twenty or so standard shortcuts (copy, paste, undo, save, find, bold, italic and their neighbours) covers a large part of this section. The FIA LDC and Sub Inspector papers from 2021 are the main past-paper sources here. Candidates who use Office daily will find the questions easy; those who have not will find the explanations give exactly the menu path or shortcut needed.
