Improved Stability
In fact, finding a free app to prepare for the IELTS exam is not hard anymore. However, there is a problem that many of these app only upload materials without considering if these resources are actual helpful. As a result, IELTS self-learners probably fall into material matrix and they are more likely to choose wrong materials.
Honestly, I used to be a victim of these kinds of website and app and I wasted a lot of time on materials which did not help me improve my IELTS score anymore!
To help you avoid my mistake, I suggest you to use this app.
