The cost of candidates applying for the Second Construction Project is affected by the region, the type of remedial classes, the quality of teachers' teaching and other factors, and the final specific cost is different. Candidates can call the local training class and then choose a favorite class for training. If you think the cost is too high, you can also choose to teach yourself. This scheme is suitable for some candidates with good foundation, strong ability and perseverance. You can save a lot of money by buying related textbooks online and then reading textbooks, learning courses and doing problems yourself.
