I've turned this from giving all of the statements first (which required much scrolling up and down), to several one-from-a-list parts. I think it's easier to work with. 

The setup of this question was extraordinarily complicated, with dozens of variables. I've removed basically all of them, and added the random names extension.

It's checkpointed below, should anyone wish to revert to the original.

The layout could be better. I think a single statement followed by multiple choice images may be easier to work with.

Hi, I'm not sure how to name the right graphs in the advice comments and I also (for reasons unknown to me) needed to change the order of the marking matrix to get it to mark correctly.

Hmm, might need Christian's help with this one; something to do with the timing of the variable replacements I would guess. However, could the 'numbering' not be placed outside of the SVGs here? So that they are static, whilst the images are shuffled?

Cannot get the variables to work inside our image function :(

I need help formatting the images I think

Created this.

There is only one version of this question.

Give any introductory information the student needs.

No variables have been defined in this question.

Numbers between and (inclusive) with step size
A random number between and (inclusive) with step size

This variable is an HTML node. HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

Describe what this variable represents, and list any assumptions made about its value.

Error in variable testing condition

There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.

No parts have been defined in this question.

Select a part to edit.

Ask the student a question, and give any hints about how they should answer this part.

The correct answer is an equation. Use the accuracy tab to generate variable values satisfying this equation so it can be marked accurately.

Advanced settings


Checking accuracy

Define the range of points over which the student's answer will be compared with the correct answer, and the method used to compare them.

Variable value generators

Give expressions which produce values for each of the variables in the expected answer. Leave blank to pick a random value from the range defined above, following the inferred type of the variable.

Base marking algorithm

                                        
Custom marking algorithm


Test that the marking algorithm works

Check that the marking algorithm works with different sets of variables and student answers using the interface below.

Create unit tests to save expected results and to document how the algorithm should work.

There's an error which means the marking algorithm can't run:

This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.

One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.

Run this script the built-in script.

This script runs after the built-in script.

To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.

In order to create a variable replacement, you must define at least one variable and one other part.

Variable Answer to use Must be answered?

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:

These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
