The student is shown a diagram containing a single point at the origin. They must move the point to the given integer coordinates.

The student is shown a diagram containing a line between two points. They're given a gradient and $y$-intercept.

They must manipulate the line or the points so that the line has the given gradient and $y$-intercept.

Given the moment of inertia of an area about an arbitrary axis, find the centroidal moment of inertia and the moment of inertia about a second axis.

This question provides practise on calculatin ga ratio from data given in a table.

These questions focus on finding a ratio (or fraction) from the information given.

Implicit differentiation.

Given $x^2+y^2+dxy +ax+by=c$ find $\displaystyle \frac{dy}{dx}$ in terms of $x$ and $y$.

Also find two points on the curve where $x=0$ and find the equation of the tangent at those points.

Given $x^2+y^2+ax+by=c$ find $\displaystyle \frac{dy}{dx}$ in terms of $x$ and $y$.

Using differentiation to find the tangent and normal to a line at a given point

Multiple choice question. Given a randomised polynomial select the possible ways of writing the domain of the function.

Given vector $\boldsymbol{v}$  find the norm. Since putting in square roots is tricky, actually input the square norm, so it's an integer.

Checking whether a given set is a plane or not. Depends on whether two vectors are parallel or not. Then checking whether the plane goes through the origin. This is not always obvious from the presentation.

Not randomised because it's the same as in our workbook.

5 questions on  confidence intervals and hypothesis testing. Population variance given, z-test. Not given, t-test.

A question designed to demonstrate the exam-level variable overrides feature. The student must work out the median of a given sample. The exam can override size of the sample, the range of numbers to pick, and whether the sample should be shown to the student in increasing order.

A graph (of a cubic) is given. The question is to determine the number of roots and number of stationary points the graph has. Non-calculator. Advice is given.

Given an ascending sequence of numbers, finds the index in the sequence of the first number greater than or equal to a given value.

Obosolete: there's now a built-in function sort_by.

Defines a custom function sort_by to sort a list of lists by the elements at the given index.

You could do a similar thing to sort lists of dictionaries.

Demonstrates how to set up a "choose one from a list" part where the number of choices is randomised.

The part is given a list of labels for the choices as well as a list specifying the marks to award for each choice.

Choose which of 5 matrices are in a) row echelon form but not reduced b) reduced row echelon form c) neither.

Simple probability question. Counting number of occurrences of an event in a sample space with given size and finding the probability of the event.

This is my first question.
