Hi, I see you're after help with maths/calculus. I'd love to help.
My name is Ross (from the UK), and I am currently studying a Masters in Nuclear Physics at University. Whilst I my subject of choice is physics, much of my education has focused around maths (it surprisingly makes up over half of my degree).
I'm not a qualified teacher or tutor but I do have experience tutoring students from ages 18 in A-levels right the way up to mature students studying maths degrees. Being a student (like yourself?) I do think much of the material you are covering I may have already covered, and fairly recently for the matter. I see you're only after the one hour per week which is cool, if you require more or less as the weeks go on then i'd be more than willing to do more or less.
If you like the sound of what I have to offer or wish to ask further questions please feel free to contact me.
Ross Clements
