The length of time to read a language is determined by the gap between students' own English level and the English level required by British schools. Students with large gaps spend more time reading the language, while students with small gaps spend less time reading the language. According to the requirements of the British Consulate, generally speaking, the IELTS score is 0.5, and I will go to the UK to study the language for 4 weeks. However, according to the experience of Bojun Education Foundation, it takes students to study very hard to improve IELTS score by 0.5 in four weeks. It is suggested that students can prepare for longer study if they have enough time and funds.

The preparatory course usually lasts for one year, including two semesters. Some universities in Britain provide students with spring admission and six-month pre-master courses, but these universities are often not very good universities in Britain, ranking basically below 40.
