The OET is an exam designed to prove the English proficiency of medical professionals and is tailored to people who wish to move to certain countries (like the UK) in order to join the medical profession As such, it is a great option because it is more career-specific than general language exams like IELTS.
OET candidates must choose which version they want to take. There are various healthcare sectors catered for, including dentistry, dietetics, nursing, and optometry. One of the given choices is pharmacy, which of course would be the choice for people wishing to go abroad to work as a pharmacist.
