Placeholders are useful for inserting the text of parts and answer boxes at specific points in the question. There are two types of placeholders:
- part's placeholder (discussed below)
- answer box placeholder (discussed on the next page)
The part's placeholder allows inserting the text of a part at a particular point in the main question. The placeholder name is a string starting with # and followed by a string of alphanumeric characters [A-Z a-z 0-9], such as #1, #a, #a1, #1a, #SubQuestion01, etc. Note that although the designation of the part's text placeholders is quite flexible, a simple designation such as #1, #2, #3, etc. is often sufficient.
At the point of insertion into the main question text, the placeholder name must be enclosed by curly braces { }. In the parts, the placeholder name is specified in the field called Placeholder name.
Use part's placeholders in the main question to insert the text of three parts.
General Question name* A Formulas question with three part's placeholders Main question Question text* With part's placeholders Two subquestions on addition: {#1a} {#1b} One subquestion on subtraction: {#2} Part 1 Part's mark* 1 Answer type Number Answer* 7 Grading criteria* Absolute error == 0 Placeholder name #1a Part's text What is 3 + 4? Part 2 Part's mark* 1 Answer type Number Answer* 9 Grading criteria* Absolute error == 0 Placeholder name #1b Part's text What is 4 + 5? Part 3 Part's mark* 1 Answer type Number Answer* 3 Grading criteria* Absolute error == 0 Placeholder name #2 Part's text What is 9 − 6?

The same question can be obtained as follows. However, it is usually easier to use placeholders as above.
General Question name* A formulas question with three parts and no part's text placeholders Main question Question text* Without part's text placeholders Note: In general, it is more convenient to use placeholders as is done above. Part 1 Part's mark* 1 Answer type Number Answer* 7 Grading criteria* Absolute error == 0 Placeholder name Part's text Two subquestions on the addition: What is 3 + 4? Part 2 Part's mark* 1 Answer type Number Answer* 9 Grading criteria* Absolute error == 0 Placeholder name Part's text What is 4 + 5? Part 3 Part's mark* 1 Answer type Number Answer* 3 Grading criteria* Absolute error == 0 Placeholder name Part's text One subquestion on the subtraction: What is 9 − 6?
