Which is better, IELTS, TOEFL or sat?

For overseas students, IELTS and TOEFL are the thresholds for our mobility, as well as sat. For many students, the difficulty coefficient of self-study is relatively large, so they will choose some training courses. So when choosing IELTS, TOEFL and SAT training courses, I don't know which one to choose. Which one should I choose? So, what factors should be measured when choosing IELTS and TOEFL training courses?

First of all, look at the brand and scale;

Secondly, it depends on the curriculum system. Many organizations are in different stages. You should also choose different learning stages (with good or bad abilities) according to your actual situation, which can also save time and effort.

Then, we need to see how their teachers are, after-sales (for a simple example, our goal is 6.5 points, what if we don't meet the standard? ), traffic and so on.

Of course, some people will consider the cost of training institutions. Many institutions have different costs. As the saying goes, value for money. When we consider the cost, we can also consider the mode and effect of after-sales and class. After all, what we want is the result (TOEFL scored an ideal score).
