what you need to know
to pass Maths at GCSE or Edexcel IGCSE?
You’re in the right place!
Grade 4 Essentials for GCSE Maths will boost your confidence and understanding, and leave you feeling ready for just about anything that the Foundation GCSE can throw at you!
It’s ideal for home educators, adult learners, and anyone else who feels they would benefit from a bit of topquality support to give them the best possible chance of that magic Grade 4.
It covers all the topics you need to be comfortable with, in order to be confident of getting a secure Grade 4 – possibly even a Grade 5 – in GCSE Maths.
It’s also suitable for anyone doing the Edexcel International GCSE (IGCSE), since there’s very little difference between the two qualifications at Foundation level. Where there are significant differences, these are highlighted.
The Grade 4 Essentials course is divided into four modules:
 Module 1: Number and Ratio
 Module 2: Geometry and Measure
 Module 3: Algebra and Graphs
 Module 4: Statistics and Probability (this module)
… and there’s also a supplementary extension module covering the few Topend Topics that aren’t included in the main course, so that you get full coverage of the entire Foundation Tier.
There’s no obligation to do all of these; you’re welcome to just do the modules that you think will be of most benefit to you personally.
How to use this course
The modules can be completed in any order, but it’s recommended that you start off with Module 1 Section 1, and that you work through the lessons in each module in the order shown – though it’s a good idea to mix up topics and revisit them in between studying different areas (this is called interleaving). You can revisit each lesson as many times as you like.
Each module consists of three sections, and in each section there are:
 multiple video lessons (averaging over 6 hours per module)
 supporting handouts that you can print out (though you can manage without most of them if you don’t have access to a printer)
 quizzes for you to check your understanding
 links to free online resources that you can use for additional practice.
The video lessons include lots of opportunities to practise the skills being taught. To make the most of each lesson you should pause the video when prompted, and try to answer any questions that have been set, before you continue watching to see the solutions. If you’re not able to do the questions straight away then don’t worry, but try to reveal the solutions just a bit at a time, then pause again and make some progress on your own before revealing the next bit. So although the running time of each video is usually between 5 and 15 minutes, if you use them properly then they’ll take you considerably longer.
Once you’ve completed all the lessons, you qualify for a completion certificate, which you can download for free. Since the aim is to build your confidence and skills rather than to hit an arbitrary number of correct answers, completion only requires you to work through all the lessons, not to achieve a particular score on the quizzes. The quizzes are more of a tool for you to check how well you’ve understood and remembered the material.
If you’re confident that you don’t need some of the lessons then have a go at the relevant quizzes first. If you get the questions for those lessons right then you can probably get away with skipping them (though you may miss out on some useful nuggets of information), but if you don’t then it’s definitely worth working through the lessons.
Of course, you will also need to practise exam questions. This course series focuses more on the underlying skills. There are great – and free – collections of exam questions by topic, with solutions, available from Maths4Everyone, SaveMyExams and JustMaths, as well as complete past papers on various sites. For GCSE you don’t just need to stick to your own exam board; questions from all boards are worth doing.
Constructive feedback is always welcome… and, for a limited period, if you like one module enough to leave a 5star review then I’ll give you a code to get another module FREE!
