+                The exam consists of 100 questions, all of them multiple choice with two or three options, which are designed to test your knowledge of a wide range of rules. For each question, answer what decision you would give as a referee unless the question instructs otherwise.

+            <li>
+                We would remind candidates that whilst we are relying on your honesty in this test, your theory knowledge will make up a part of the practical assessment when you are observed refereeing a game.

+            Questions in the test are arranged in blocks. Blocks can be of two types: <strong>Blocks</strong> of multiple related questions, and <strong>Single Questions</strong> that are not part of a block.
+            You can add, remove, or edit both Blockss and Questions through this editor.
+        </p>
+        <p>
+            <strong>Blocks</strong> are useful when you have a section of the test that contains multiple questions that are related to each other, for example if there is a scenario-based section where a series of questions are about the same situation.
+        </p>
+        <p>
+            Blocks can contain any number of questions within them, but cannot contain nested blocks.
+        </p>
+        <p>
+            When you set up a block, you can also add <strong>header text</strong> that will be displayed with each question.
+            You can use this to provide common information for a scenario across a series of questions.
+        </p>
+        <p>
+            Questions come in three types:
+            <ul>
+                <li>
+                    <strong>Yes/No</strong> for when there is only a yes or no option, 
+                </li>
+                <li>
+                    <strong>Multiple Choice</strong> for your regular multiple choice questions, and
+                </li>
+                <li>
+                    <strong>Ordered List</strong> for multiple choice questions that will be displayed in the same order as listed here.
+                </li>
+            </ul>
+        </p>
+        <p>
+            Normally, multiple choice questions will have the order of the options randomised.
+        </p>
+        <p>
+            Questions will be displayed to candidates in a randomised order.
+            Blocks of questions will be kept together, but the order within the block will also be randomised.
+        </p>
+        <p>
+            Questions can also be categorised using <strong>tags</strong>.
