Question in Antony's workspaceThe matrix entry part in this question marks any symmetric matrix as correct, using a custom marking algorithm. A matrix is symmetric if it is equal to its transpose.

Exam (6 questions) in francisco's workspaceDivisibilidad, factores primos, mínimo común múltiplo y el máximo común divisor de números dados.

Question in Daniel's workspace
$I$ compact interval, $g:I\rightarrow I,\;g(x)=ax^3+bx^2+cx+d$. Find stationary points, local and global maxima and minima of $g$ on $I$

Question in Howtos
This shows how to implement a recursive function in JavaScript with a nested function definition.

Question in Adrian's workspace
This uses an embedded Geogebra graph of a line $y=mx+c$ with random coefficients set by NUMBAS.

Question in Howtos
The student is asked to write a number with a certain property, or tick a box labelled "this is impossible" if it can't be done.
A custom marking algorithm on the gapfill part first checks if the student ticked the box. If they did, their answer is marked correct if it really is impossible. If they didn't tick it, their number is checked against the required property.

Question in Howtos
The student is shown two number entry gaps on either side of a 'less than' sign. Their answer is marked correct if the first number is less than the second, using a custom marking algorithm.
This shows how to mark the gaps in a gapfill part together, rather than independently.

Question in Howtos
A diagram showing the difference between lines, rays and segments in Eukleides.

Question in Howtos
Shows how to use the "random person" extension to pick random names for people in your questions.

Question in Howtos
This question shows how to load a GeoGebra applet from geogebra.org.

Question in Howtos
This question randomly generates a list of 100 items, each chosen from a list of strings.
It then computes the number of occurrences of each distinct item in the list. The statement shows the frequencies in a table.

Question in Howtos
This shows how to define a question variable whose value is a variable name with a few annotations added, so it's more convenient to use.
The question variable 'x' is defined to be the variable name
vec:underline:x
. 
Question in Howtos
The student is given a value of $\cos(\theta)$ and has to find $\theta$.
Shows how to use subexpressions to represent randomlychosen fractions of $\pi$ and surds, and have them displayed nicely.

Question in Howtos
Shows how to create a simplified JME subexpression, and substitute it into a string variable.

Question in Howtos
To prevent students from giving a trivial answer for a part which is used later in adaptive marking, you can consider it as invalid.
Part a of this question has a custom marking algorithm which marks an answer of zero as invalid. Any other answer is used in adaptive marking for part b.

Question in HowtosA custom marking algorithm picks out the names of the constants of integration that the student has used for the $\cos$ and $\sin$ terms in their answer, and replaces them with $A$ and $B$ respectively, before comparing with the correct answer. This way, the student is free to choose the names for their constants of integration.

Question in Howtos
Use the bareMatrices display flag to render a matrix without wrapping it in parentheses.

Question in HowtosThis question shows that you can set the number of marks available for a part to a fraction. The total available for the question is 1 mark.

Question in Howtos
A demonstration of how to use the "variable list of choices" option for a "choose one from a list" part to shuffle only some of the choices, and always have the same "I don't know" choice at the end of the list.

Question in Howtos
This question uses a "formatted text template" variable to define a long passage of text which is shown to the student after they submit a part. A custom marking algorithm adds the text as a comment after the standard marking algorithm has finished.

Question in Howtos
This question uses the linear algebra extension to generate a system of linear equations which can be solved.
We want to produce an equation of the form $\mathrm{A}\mathbf{x} = \mathbf{y}$, where $\mathrm{A}$ and $\mathbf{y}$ are given, and $\mathbf{x}$ is to be found by the student.
First, we generate a linearly independent set of vectors to form $\mathrm{A}$, then freely pick the value of $\mathbf{x}$, and calculate the corresponding $\mathbf{y}$.
To generate $\mathrm{A}$, we generate more vectors we need, then pick a linearly independent subset of those using the
subset_with_dimension
function. 
Question in Howtos
The gapfill part in this question is only marked correct if both gaps are correct.
The feedback from the individual gaps is not shown.

Question in Howtos
A custom marking algorithm for a JME part estabishes whether the student's answer is equivalent to the expected answer, up to an arbitrary constant factor.

Question in Howtos
This question shows how to use the 'adviceDisplayed' signal to run some javascript when the question's advice is revealed to the student.

Question in Howtos
This question includes a JavaScript preamble which defines 'hbar' as a special variable name to be rendered in LaTeX as \hbar.

Question in Swansea Electronic and Electrical Engineering
A preclass test for week 2.
