Maths tutor providing lessons, difficulty to be discussed by message, preferably GCSE or A-level

I am a student going on to studying Computer Science at the University of Warwick. I have GCSE grades of 999999887 with a 9 in Maths and 8 in Further Math. I am predicted A*A*A in my A-levels which are Maths, Further Maths and Computer Science. Although minimal official teaching experience, I regularly teach concepts to my classmates and receive good feedback. I am happy to take the time to explain difficult mathematical concepts to a high degree and I aspire to do my best!
