Introduction [Heading 1]

To write your report, we are required to use the formatting that is permitted as detailed below and shown in the Styles list (see Styles section in the Home banner). This will ensure that everybody hands-in a similar document and that all those documents can be neatly put together.

MS Word (2010 and above) for Windows is the preferred editor to be used to prepare your report. However, this template should work with MS Word for Mac as well.

To apply a Style, you must first type the text (e.g. in the default Normal style), then select it, and finally apply the style by selecting it in the Styles list. In the rest of this document, each style is shown in brackets “[…]” the first time it is applied.

If you experience any issue with the formatting

Sub-section [Heading 2]

Use sub-sections and sub-sub-sections whenever needed, in order to structure your text. [Paragraph]

This is a Paragraph. Within the text, you can emphasize [Emphasis] text, bold [strong] text or underline [Underline] text. You can also use subscript [subscript] and superscript [superscript] formatting. Do not use standard short-cuts for character formatting (e.g. Ctrl + i), but use the pre-defined character styles.

Note that, like in any other scientific work, it is important to make proper references. Please use “(Lastname, Year)” citation formatting. Then, all references go at the end of your document in the section References (see below).

Figures and tables are allowed. They must be inserted as shown below. Both of them should be inserted “as character”.

[Figure]

Figure 1: The figure’s caption [Caption]

Table Header [Table Content Left + Strong]

Table Content left [Table Content Left]
