When it comes to IELTS training, Lange is a company that can't be avoided. As the first language training institution in the country to advocate small-class education, Lange has achieved an annual revenue of more than 500 million yuan in more than ten years. Founded in 1999, Lange is in the prime of its life in the training industry, and currently has at least 50 campuses in 31 cities including Shanghai, Beijing, Nanjing, Wuxi, Guangzhou, etc., and was rated as a Class A school unit in 2002, and was awarded the title of IELTS official platinum partner in 2014, maintaining a score rate of 88%-91% all year round. The curriculum system and class types of Lange are relatively simple. The initial stage (96 hours) and the preparatory stage (96 hours) are introductory, which mainly train students to think about abstract things, and be able to discuss IELTS hot topics in English, and use a certain number of clauses in the discussion; The foundation stage (96 class hours) and breakthrough stage (64 class hours) are suitable for advanced level learning, which expands the depth and breadth of understanding IELTS questions in the course, sorts out the test mode and solution skills of various question types, and achieves a correct rate of more than 50%; The high-quality stage (128 class hours), the 65 stage (64 class hours) and the seven-point sprint (128 class hours) are intended to score points, and through high-density brushing of mock test questions, practice makes perfect in the four subjects of IELTS, listening, speaking, reading and writing, and at the same time cultivate a stable level of on-the-spot performance and psychological quality, ensuring that more than 65% of the questions are correct and 6.5 or even 7 points or more. The above courses have 3-6 people in small classes and 10-12 people in medium-sized classes to choose from, the teaching content is the same, the cost gap is about double, the small class is 95 yuan per class hour, the medium class is 48 yuan per class hour, the price diving is large, you may wish to try to bargain before signing up. If you do not meet the IELTS score within one year after the end of the course, you can retake the same type of course for free. It should be noted that small classes guarantee the total score and individual subject scores, and medium classes only guarantee the total score. Lange's current product line is still mainly based on study abroad training, of which IELTS is the majority, and the relatively low price has attracted the favor of many students. It is worth noting that although Lange claims to receive official teacher training and certification from ETS every year, in fact, the level of teachers is still uneven, of course, there are famous teachers, but there are not a few cases of graduates teaching, and even there are problems in basic skills such as pronunciation. There are also many criticisms such as the unsatisfactory classroom environment, the space is small and not ventilated, the place for testing and consultation is a public area, and the noisy environment will affect thinking. In addition, there is only one campus in Guangzhou, and the transportation is not convenient.
