Experts in Science and Maths

Our extensive teaching experience enables us to communicate difficult ideas and concepts at the right level for our students.

Comprehensive notes

We provide our students with a comprehensive range of teaching notes, tailored to each module. Our teaching materials are designed with students’ needs in mind.

Innovative teaching techniques

We believe that students do best when they participate actively in the process of their own learning, by applying innovative teaching techniques, including active learning, peer-teaching and self-correction.

Small group size

Our students thrive because they are given the undivided attention and help that they need on an individual basis. That is why we limit our classes to a maximum of 10 students.
