TestGen has controls for displaying both workspace within a question and spacing between questions on tests.
Some testbanks (for math, in general) have a preset amount of workspace assigned to each question by the testbank author to allow students space to write their answers or show their work on a paper test. By default, this workspace does not show up on a test when you transfer questions from the testbank.
To make the assigned workspace, if available, display on tests as you transfer items from the testbank, select "Preferences > Application" from the Tools menu and change the workspace setting on the Transfer Options tab.
Note: This setting applies only as you transfer items from a testbank. After test items are on the test page, you can adjust spacing between questions either globally, affecting all questions on the test, or manually, on an item-by-item basis. To adjust workspace values in a testbank, open the testbank in the edit window, select a question, and display the Properties window for the question.
To adjust the blank space between questions globally, affecting all questions on the test, go to the Default Styles tab of the Test Options dialog. Use the settings in the Spacing section to set a preference for spacing between questions that applies to the current or future tests.
To adjust the spacing between test questions on a case-by-case basis, do either of the following:
Put the cursor at the end of the question field and press the Enter or Return key one or more times to add blank lines. If there is too much workspace at the end of a question, put the cursor at the end of the workspace and use the Backspace key to delete the unwanted lines.
Put the cursor in the one-line editable field between questions and press Enter or Return to increase the space between two questions.
