It's true. Courses are divided into agreement classes and non-agreement classes. Agreement classes are non-refundable.

As long as the results are not caused by personal reasons, they can be refunded normally. Personal reasons include not taking the exam and cheating in the exam.

If it involves a late refund, you need to bring a copy of your ID card, a copy of your bank card, a receipt, an agreement, etc. Please consult your local customer service teacher for specific requirements.
