Studying abroad requires a certain English foundation, otherwise you can't live a normal life even if you go abroad. Language barrier is the biggest obstacle. By training IELTS, you can make yourself more competitive. If Henkel can achieve his goal as long as he spends on training, that's good. What if you go out and your English level is not up to standard? You can ask more questions, or you can train IELTS before choosing an institution to study abroad. In fact, each language institution has its own partner, you can choose or not. As long as it is good for your tomorrow, I suggest you reconsider. It is best to choose the most sure way to achieve your goal easily.
