1. Economic affordability: For some people, a class in 300 yuan may be a big expense, while for others, it may be an acceptable price. Therefore, whether this price is expensive or not depends largely on the individual's economic ability.

2. Demand for private education courses: If private education courses are only needed occasionally, or fitness purposes can be achieved by other means, then the price will be considered high. To sum up, 300 classes in private education are very expensive.
