! I would like to ask the second-level construction engineer, which is better to take the exam, which is better to hang up and which is more expensive (I graduated from computer secondary school).

For your professional knowledge level, the difficulty of the two majors, municipal administration and water conservancy, is the same. The affiliated fees of the two majors change with the market demand. Generally speaking, the cost of water conservancy is high, but there are few units needed, and sometimes it is not necessary to find affiliated units. Municipal prices are slightly lower, but many units are needed. You should weigh yourself and make a choice.
