Many students want to know how long it will take to get the score they need. It's impossible for me to answer this question because it depends on too many things. For example:
- How many hours of study do you do each day?
- What kind of study do you do?
- Do you have a teacher or someone who can help you?
- Do you live in an English-speaking country?
- Do you like learning English, or do you just need an IELTS score?
Maybe the last question is the most important one. In my experience, people who enjoy learning English tend to make the fastest progress.
