Virtual A-Level Edexcel Maths student looking to teach younger years, preferably GCSE or younger years

I am currently studying A-Level Mathematics and have attained an A grade during my first Pre-Public Examinations for the Pure exam, Edexcel and attained a 7 grade at GCSE for Maths. I aim to be able to help students understand topics, and why we do different things in Maths as sometimes it may get confusing for children from younger years. Being able to understand a topic is the first step to mastering it.
