Courses
Meeting your needs
We understand that our students are of different age-groups and abilities, come from different backgrounds
and have different personal and professional reasons for wishing to improve their language skills. Small class
sizes (maximum 10 students) ensure that individual learning needs can be satisfied.
Confidence-building environment
Our highly qualified, friendly staff will ensure that when you come on one of our courses, you will be treated
as an individual (个体) and will be provided with the opportunity to learn language skills at a level and pace
which suits you. In this way, you can feel sure that we will enable you to maximize (最佳化) your learning
potential (潜能), while making sure you always feel comfortable and confident to communicate in the language
you have chosen to study.
Course Length
There is no fixed course length, as we feel it is important to be flexible (灵活的), in order that students can
decide what period of study suits them best. Providing there is a free time at an apptopriate (适当的) level,
students can come and learn at our school for a period of a week. Why not sign for your first week now? We're
confident you'll be coming back for more!
Course types
We offer a full range of group and one to one courses, at all ability levels. Most of our courses are taught
in-house at our school in Richmond however we can also organise in-house training for your organization. We
offer a range of full time General English courses, English exam courses leading to a recognized qualification
(资格),Business English courses, special English Summer courses and a wide range of Foreign Languages.
Please note that the minimum age for students on all our group courses is 16, younger learners are taught via
individual one to one tuition.
