怎樣安排下雨天的戶外課?What is the arrangement for outdoor classes in rainy days?

如果上課日天氣持續下雨以致地面濕滑,本會會於上課前一小時以電話通知取消,已付之學費亦會順延。如果上課途中下雨需要暫停而上課時間少於15分鐘,該課之學費亦會順延,多於15分鐘則作一課計算。
If the day keeps raining and causing wet floor, our school will contact students by phone about the class cancellation. Paid lesson will be extended. If the class is suspended less than 15mins since started because of rain, that lesson will not be counted. However, if lesson have started for more than 15mins, it will be counted as 1 lesson.
