What is the probability that a GCSE student feels ready for their maths exam? With enough practice, that probability can be high! If you’re looking for additional support, our professional GCSE maths tuition can help you build the confidence you need to ace your exam.
Our tutors use a huge library of targeted teaching resources, including video explainers, graphics and banks of exam-style questions, to deliver personalised support. Here is a set of ten probability GCSE questions from our library.
