1, Jiangsu and Zhejiang are unified exams, and the content and time of the exam are the same, so there will be no difference in difficulty.
2. Studying abroad may not be able to take the exam in Jiangsu. Jiangsu's requirement is to provide the graduation certificate and degree certificate of the place where the household registration is located to take the exam. If it is a school certificate, the school needs to be in Jiangsu. But I'm not sure. I suggest you consult the Education Bureau directly.
3. Studying in Zhejiang can be tested in Zhejiang, and Zhejiang requires undergraduate seniors to take the test.
In addition, no matter where you get the teacher qualification certificate, it is universal in the country.
There are other questions about teacher qualification certificate.
