To illustrate how to do partial scoring with Dynamic Parameters, we will create a trivial question of adding two to a number:

Note that @a is the dynamic parameter that will contain a range of values and @c will be the correct answer in this case that gives Full Credit of **2** points. We will create an *alternative answer* for Partial Credit of **1** point. We will use a different parameter for this answer, @d:

The dynamic parameters should be given as follows:

Then we use PREVIEW mode the check the evaluation:

Case of a **correct** student response:

Case of a **partially** correct response:

Case of an **incorrect** response:
