Convert a height given in feet and inches into cm and then metres.

This question assesses the student's ability to use some given information involving two different units of measurement to rewrite the information as a compound measure.

This question assesses the students ability to calculate and convert between different types of compound units, including rates of pay, speed and unit pricing.

Given the cost of hiring a room for a given number of hours, compare with competing prices given per hour and per minute.

Converting between giga, mega, kilo, base, milli and micro, nano. Metres, grams and litres.

Straightforward question: student must find the general solution to a second order constant coefficient ODE. Uses custom marking algorithm to check that both roots appear and that the solution is in the correct form (e.g. two arbitrary constants are present). Arbitrary constants can be any non space-separated string of characters. The algorithm also allows for the use of $e^x$ rather than $\exp(x)$.

Unit tests are also included, to check whether the algorithm accurately marks when the solution is correct; when it's correct but deviates from the 'answer'; when one or more roots is incorrect; or when the roots are correct but constants of integration have been forgotten.

Practice of conversion between SI units of mass, volume & length.

Elementary operations on vectors; sum, modulus, unit vector, scalar multiple. 

Converting a length in m to mm, cm and km.
