Parents are advised not to sign the bill after the first chat, but to go back and think calmly. What are you thinking about? Do their counselors ask you more about your income and sell you courses to ensure the effect, or do they carefully examine your study, make a counseling process that you think is appropriate, and have a detailed effect guarantee plan (it is definitely not enough to just pat your chest).
Usually their counselors are very professional, and anxious students and parents can't cope with the first round. Parents must think carefully. Did he talk to you for a long time about your money, or did he sincerely introduce their services to you and let God make a choice. If it is the former, it is best not to go.
Teachers should also investigate clearly, and it is best to get a free audition opportunity, and remember, don't pay in one lump sum. Even if it is their so-called regulation, as a consumer, you have the right to choose, and you can pay by installments according to the training effect. If an institution that doesn't even dare to promise this is usually a fool, because it has no confidence in her training guarantee, then the guarantee made before is obviously a fool.
