Primarily concerned with identifying when a number is in the thousands, million, billions or trillions.

Students are shown a graph with 6 vertices and asked to find the length of the shortest path from A to a random vertex.

There is only one graph, but all of the weights are randomised.

They can find the length any way they wish. In the advice, the steps of Dijkstra's algorithm used in solving this problem are displayed. It is not a complete worked solution but it should be sufficient to figure out the shortest path used to reach each vertex.

Short question to test encoding some random binary strings using repetition and parity bit. Randomised 5-bit strings.

A question that will allow students to check their understanding of the Caesar Cipher by encrypting a short message given a random key. May be updated with a decryption task later.

Short question in recognising errors in binary strings transmitted over a binary symmetric channel, as well as calculating probabilities of these errors occuring. Randomised 7-bit strings between 64 and 128, randomised probability between 0.05 and 0.1. Randomised error pattern.

Given a randomised rational function select the possible ways of writing the domain of the function.

Attempt to apply Dijkstra's algorithm to find the shortest path from the source node (a) to a given sink node.

A short demonstration of when the basic simplification rules are turned on, or off.

This exam tests one's ability to do simple maths quickly, using shortcuts where possible.  It is a diagnostic test so the results are to let us know where you need help.  Please take a screenshot of your final score and forward to WSY.

Welcome the the first stats quiz! It's very short. 

• You have 25 minutes.
• There are 3 questions (with parts). The topics are measures of central tendency and measures of spread.
• Enter all of your answers and keep 2 decimal places. 
• Submit them as you go to make sure you don't carry mistakes. You can't change your answer once you've submitted it.
  

Write down on a sheet of paper the data you are given, along with your detailed calculations. Submit a picture on google classroom. 

Let me know if you have any questions!

Good luck!

Add, subtract, multiply and divide algebraic fractions.

Some quadratics are to be solved by factorising

$x$ is given and (sin(x),cos(x)) is plotted on a unit circle.  Then the student is asked to determine sin(y) and cos(y), where y is closely related to x (e.g. y=-x, y=180+x, etc.)

Short Video Lectures, followed by questions and video solutions

A few quadratic equations are given, to be solved by completing the square. The number of solutions is randomised.
