The disadvantages of this kind of training course are lack of scientific basis and high cost.

1, lack of scientific basis: the teaching methods of some training courses of super brain, such as "super memory method", are actually a memory coding skill, not a real improvement of brain function.

2. High fees: Some training courses of Super Brain are extremely expensive. For example, for the 20 19 year disciple class of Wuhan Oriental Dragon Education, the primary school students charge15,000 yuan, and the junior high school students charge17,000 yuan.
