拒签原因是这样写的：
ECO Comment:
You have claimed 30 points for a valid CAS but your CAS was assingned after 11 August for a non-English language course which is below NQF Level 6. Your sponsor is there fore required to ensure that you have passed an English language test from the list of approved tests for Tier 4 and to detail this test, including abreakdown of the scores achieved in each component of the test, on your CAS. Your sponsor has not done so.
I am there fore not satisfied that you have a valid CAS and you have not been awarded any points for the CAS. You therefor do not meet the requirements to be granted entry clearance under Tier 4(General) Student and I refuse your application under paragraph 245ZV(b) of the Immigration Rules
PS：我递交了我的雅思成绩还有高中毕业成绩，这都是我的学校要求我提供的，我都已经提供了，很奇怪被拒原因为什么还是英语语言成绩之类的问题。
