It is more secure for brand training institutions to refund money. In terms of refund, it can be done that the agreement does not refund your money, but most of them will explain how much you will only refund when signing the contract. They will charge a certain basic fee and refund a certain percentage of the training hours, not all. And if the regular class passes, there will be a charge.
What class to enroll in depends on your actual situation. If the economic conditions are ok and the written test rankings and scores are good, you can consider signing up for an agreement class. If you just want to feel how training institutions carry out training strategies, then you can make full preparations yourself. In order to save money, you can sign up for an ordinary class.
I was admitted to public institutions and civil servants, and cooperated with some institutions to organize public welfare training for civil servants and college students in public institutions for four years. I have heard of the training of professional teachers. Generally speaking, I feel that it is much more efficient to have someone to teach Raiders and special courses to prepare for the exam wholeheartedly than to prepare for the exam alone. If I have the conditions, I can choose to enroll in the class.
Regardless of whether to report for class or not, the most important thing is that individuals should prepare wholeheartedly and constantly brush the questions. Moreover, there are abundant network resources, and you can find relevant video and text experiences online for free, where there is a lack of targeted supplements.
