The IELTS syllabus is divided into four modules: reading, speaking, listening, and writing. Every module has a different concept. Here is a brief overview of all the modules:
The reading module is divided into three passages with 40 questions. The passages cover a variety of topics taken from Books, Journals, Magazines, and Newspapers. You can expect question types such as Multiple Choice, Matching headings & features, etc. These passages test students' ability to read and understand the written material. Band scores are marked out 9 and depend on the number of correct answers.
The listening module is divided into four sections A, B, C & D. Each section has 10 questions. The candidate has to listen to a conversation and answer all the questions. Band scores for listening are calculated out of 9 and depend on how many answers are correct
The writing module covers two sections, Task-1 and Task-2.
Band scores in writing depend on four main features: Coherence & Cohesion, Vocabulary, Grammatical use, and accuracy.
The speaking module includes a direct face-to-face interview. This module is divided into three sections: an introduction, a short speech, and a discussion based on the speech. Speaking band scores are calculated out of 9 and depend on four main features, namely Fluency Coherence, Lexical Resource, Pronunciation, Grammatical use, and accuracy.
