Do IELTS and TOEFL have a high chance of passing the self-taught exam?

Although many people have passed IELTS and TOEFL through their own self-study every year, they are a minority after all, and their English foundation is particularly strong. Generally speaking, the self-study pass rate of IELTS and TOEFL is still very low.

If your English foundation is not particularly strong and you don't have strong autonomous learning ability, then it is not recommended that you study IELTS or TOEFL by yourself. Choosing a suitable training institution will cost you extra money, but having a professional tutor to guide you can improve your efficiency. Coupled with your own efforts, the final pass rate is definitely not comparable to the self-study exam.
