If you need to solve them, then you just plug your way through the algebra to get to the answer.

In this question (Q7) you need to find the value of a constant such that there is no solution to the...

1. Check whether student can calculate simple interest, e.g. How much money would you have after 1 year if you have £50 and get 3% interest? (Ans: 50*1.03 = 51.50)

the linear speed of an orbiting body is given by the equation sqrt(GM/2r) where M is the mass of the attracting body, G is the gravitational constant and r is the distance between the two bodies' centres ...

The Young's modulus is a measure of the stiffness of the material - higher the young's modulus, higher the stiffness. It is calculated by dividing stress by strain over the elastic deformation region and ...

Without a doubt, the timing was the most challenging aspect.  To start with I didn’t do questions timed, just to get a feel on how to approach questions but fairly soon I started timing myself, being very...
