These classes are designed for students who want to take the IELTS examination. If you are planning to go to university or to start a job, you may need to gain a certain IELTS score. For example, to do an undergraduate course at university you require an IELTS score of 6.0 in all four parts of the test including speaking, listening, reading and writing. This is considered B2 of the Common European Framework Reference (CEFR).
If you are planning to start postgraduate studies, you may need to gain a score of 6.5 or 7.0 in IELTS, which is C1 (CEFR). Many students prefer to combine IELTS in the afternoons with General English classes in the mornings. This way, students improve confidence and fluency with training and practice in how to answer IELTS examination questions.
