Personalised Revision Tool for
Edexcel S1
Aims
This Revision Tool aims to make your revision smarter and more effective. It aims to:-
Identify gaps in your understanding and knowledge.
Give a short summary & example for each sub-topic.
Provide hyperlinks to MyMaths lessons for most sub-topics.
Using the short tests
There are 2 mini-assessments for each sub-topic.
Use the first test to identify which topics you need to work on. If you get a good
mark you will not need to use the second test on this topic.
Use the second test to measure the level of improvement after remedial work has
been undertaken.
This PRT is not a substitute for, or an alternate to, doing past papers.
A programme of completing whole past papers is essential for success.

Explanatory & Response Variables
When two variables are linked so that a change in one causes a change in the other;
The explanatory variable causes the change. It is independent and we usually plot this on the x
axis.
The response variable is changed by changes in the explanatory variable. It is dependent and we
usually plot this on the y axis.
Least Squares Regression Line
Product Moment Correlation Coefficient
