IELTS (International English Language Testing System) is the most widely recognised English proficiency test for immigration, higher education and professional registration in the UK.
IELTS Academic (for university and professional registration) tests: Listening (30 minutes, 40 questions), Reading (60 minutes, 40 questions), Writing (60 minutes, two tasks), Speaking (11 to 14 minutes face-to-face with an examiner). Scored 1 to 9 (overall Band Score, average of four component scores).
A one-month IELTS intensive preparation course at an accredited UK school typically costs £600 to £1,500 depending on hours per week and location. Good preparation courses focus heavily on Writing Task 2 (academic essay) and Speaking, which are where most candidates lose marks. Test practice under timed conditions is essential — knowing the content is insufficient if you cannot complete the test in time.
The official Cambridge IELTS Practice Tests books are the most accurate preparation materials. The British Council IELTS website and IELTS.org provide free practice materials. Band 7 Writing requires not just grammatical accuracy but also vocabulary range, coherent argument structure and the ability to address the task fully — these are harder to develop through self-study alone than through course feedback.
