Fed up with your GCSE revision? Try these new quizzes. You’ll find lots of different topics. Beware, they are designed to catch you out! The authors have thought carefully about the mistakes you are likely to make. So when you get to the end of a quiz look carefully at the mistakes you have made and make sure you understand where you went wrong.
In May 2015 the United Kingdom went to the polls. A Conservative Government was elected. The UK uses the “first past the post” electoral system. The country is divided into 650 constituencies. The candidate with the most votes from each constituency is elected.
Most other countries in Europe use various forms of proportional representation. This means that the number of MP’s for each party would be proportional to the number of votes that were cast for them. (There are many different forms of PR, but in this exercise, to keep it simple we are going to work out the number of MPs by dividing the vote for each party by the total vote and then multiplying by 650, which is the total number of MP’s in the House of Commons. )
First fill in the missing numbers in this table. You will need a calculator. Remember that to round to two decimal places you need to look at the 3rd decimal place. If this is 5 or more round the 2nd decimal place up. If it is less than 5 then ignore it. eg 34.349239=34.35 to 2dp. 2.983432909=2.98 to 2 dp.
If you got the first exercise correct I want you to illustrate your results with two pie charts. Use this table to work out the degrees for each party. You can draw them in excel or with a protractor and pencil.

If you have not yet tried Squares and Cubes do this first.
A square root is the opposite of squaring a number. The symbol for square root is √.
So if 3²=9 then √9=3
A cube root is the opposite of cubing a number. The symbol for cube root is ³ √.
So if 3³=27 then ³ √27=3
TrySquares, Square Roots, Cubes and Cube Roots to help you become familiar with the important examples of this.
To square a number you multiply it by itself. For example 3² =3×3=9
To cube a number you multiply it by itself three times. So 3³=3x3x3=27
If you are studying GCSE it is very helpful to learn the common squares and cubes to save you time in the non calculator exam. This exercise will help you do that-don’t be tempted to use a calculator! For Functional Skills students you can use a calculator. Look for the x² and x³ buttons on your scientific calculator and use these.

Here is a great phone app that will help you with your arithmetic so you don’t need to be afraid when you are faced with that non-calculator exam. It’s called Maths Tricks and shows you lots of short cuts to performing calculations and gives you endless practice to improve your speed and accuracy. Best of all it’s free!

You can find it on Google Play. I am recommending this because it is good, not because I have any connection to the app.
Here are two more practice on-line tests. When you get to the end the computer will ask you to review your answers. Go back and ensure you have answered all the questions, shown all your working and not made any silly mistakes. If everything is ok click on continue. You may have to wait a while, but eventually the computer will ask you to save a pdf. Save it, then open it. The computer will have marked some questions for you but most have to be marked by a teacher. If you have a teacher, send them the pdf and they will mark it for you.
