This institution is a training class under the Education Group of Jiaotong University, which mainly trains foreign language examination qualifications, such as TOEFL and IELTS. Note that Jiaotong University Education Group is an independent enterprise and has nothing to do with Jiaotong University. The training course only uses some retired teachers from universities such as Jiaotong University and Fudan University, and that's all.
So, this is not what your brother needs at all.
