As long as you can speak English at a fluent or near fluent level, then you are eligible to participate in the course. Non-native speakers do sometimes find the course quite challenging, so you need to be sure that you have a good level of English before you enrol.
As a guide we recommend that that non-native speakers have a minimum CEFR level C1 or IELTS 6.5 score. If you are unsure you should take our FREE online level test below and be able to score 85% on your first attempt.
