If there is no exam, theoretical training can be fully refunded. As long as you train, you will deduct half of the money.
If the training course is not refundable, you should complain to the consumer association. Students have the right to give up their studies. Training institutions stipulate in the contract that the fees cannot be refunded by "format clause" and "overlord clause". There can be an agreement between the training institution and the trainees, but the agreement cannot violate the relevant laws and regulations. Students or parents can provide payment basis and written materials to coordinate the refund. The so-called consumer complaints refer to the written or oral objections, propositions and requests that consumers put forward to solve problems due to disputes with operators in the process of purchasing and using goods or receiving services due to their daily consumption needs.
