Well,IELTS involves a lot of learning and acquisition of the necessary skills.
These skills can be acquired over a period of time,but unfortunately,the IELTS industry itself has commercialised a lot these days.So,despite taking classes from the elite and the most prominent institutes,the student's performance does not improve.
The best idea would be to find online help.Nowadays,a lot of online resources are available pertaining to the IELTS test.Just focus on acquiring the pre-requisite skills before you go ahead and get enrolled for the practice or the screening part.
A few skills that need to be taken care of include:
Note taking skills(LISTENING)
Para-phrasing skills(READING AND WRITING)
Skimming and Scanning(READING)
Brainstorming and making Mindmaps.(WRITING)
Prediction(LISTENING AND READING)
Critical Thinking(WRITING AND SPEAKING)
I shall be more than happy to assist you further on how to acquire these skills and also provide with the practice and feedback sessions.
