The tutor you need!
I took Alastair's classes in Oxford's Summer School Programme and I have to say he did a fantastic job. His lessons were very well structured and fascinating. He explained everything very clearly and would often ask questions to keep us engaged in the class. After tutorials, he would give us articles to help us read further into the topics which I found extremely helpful. I'd definitely recommend him as a tutor.
I've learned quite alot from him and Im very pleased with his tutorials.
