Junior TOEFL was a recent development from ESL and almost all of boarding schools now understand how they interpret the scores when students send scores to them. So my recommendation is to take either or both if you can as soon as possible.
Please do not delay any application because you do not have TOEFL scores. Just complete application as soon as possible and start to communicate with schools that you applied and update them with new information in the process of application. They will appreciate you.
你好: 初阶托福Junior TOEFL是近几年从ESL发展出来的,几乎得到所有住宿制学校认可并且采用这样的评比分数来评量学生程度,所以我的建议是至少也要提供其中一种分数。
请不要为了托福成绩而延误递交申请函,尽量完备申请书和开始与学校建立沟通,并且与时俱进的提供你的新进度和新数据。学校会欣然接受和谅解的。
