WMS: I was responsible for Warwick Maths Society academic support for MA106 Linear Algebra during the 2013/14 academic year. (notes from the midterm review session).
STEP: In both academic years 2012-2013 and 2013-14 I tutored a single further education student for STEP II and III examinations. Both were successful in gaining places at Cambridge. Here is a revision document that I produced for my tutees. For American students, STEP is similar to SAT.
LaTeX: I prepared this commented tex file to serve as a basic introduction and sandbox for producing graphs and commutative diagrams in tikz. After compiling, it should look like this.
