About


Wicked Maths has been born out of frustration. At first,

our own frustration as students of maths – there never seems to be a video of ‘the ONE that you need’.

You tend to get one generic example of how to do something and then a batch of subtly different questions to try. If you get one wrong, that happens to not be exactly the same as the worked example, then you’ve had it.

Our other pet-hate is when the answers in the back of the book, or on the screen in front of you, are incorrect! We usually assume that we have made the error and spend FOREVER trying to figure out where we messed up. It takes huge amounts of confidence to decide that we are right and that the ‘authority’ on the subject must be wrong.

Finally, in an exam, there is often more than one correct answer – it’s denoted as o.e. on the official mark schemes and it stands for ‘Or Equivalent’. This means that the examiner can award you full credit if your answer is equivalent (the same but in a different format). As students you cannot be expected to know all of the acceptable equivalent answers, or where they are applied, so they should be there in the answers for you.

So, here at Wicked Maths, we pledge to make you a how-to video for each and every question we ever write. We will endeavour to cover all the ‘o.e.’ answers just like you would have in your exam and we will always take great care to ensure that our solutions are correct by triple checking each other’s work and by replacing erroneous workings in a flash!

Wicked Maths Commitment

The Wicked Maths App is our commitment to sharing the strategies, mechanisms and systems that we have created to help hundreds of students over thousands of hours to be successful at GCSE.

Maths is more in alignment with learning a Modern Foreign Language, a Martial Art, or a Musical Instrument, much more so than science!

It’s about building confidence around a set of skills like; learning to play scales in music, an axe kick hard enough to break a board in Tae-kwon-do or ordering lunch in French. It requires only; motivation, practice and determination to achieve success.

“It’s about attitude, not aptitude!”

Wicked Maths is for the students who’ve been let down by poor teaching, poor leadership, or who’ve missed lessons through illness or injury. It’s for those who realise late in the day that they really must pass their exam and it is for those who decide they will not accept their school/teacher’s low expectations.

If your Maths grade is lower than the rest of your subjects, then it is likely that you’ve suffered poor teaching. We see countless students who are straight 7-9 s in ALL SUBJECTS except Maths! This is not some mystery – it’s lazy teaching, poor accountability and a lack of motivation to succeed – or all three. Often it is the teacher with these problems and not the student!
