For 3. I think this has been written on the contract, for most Montessori School, if you want to drop off, you need to notice one month ago. For example, you want to drop for Mar, you need to give the notice on Jan 31 or before 31, and there is no drop off after April
For 4. It is already written in the contract, every month has the same fee, and in September, there may be no school in the first week, in Dec, there is a long winter vacation more than one week, in Jan, it's also possible to have one week vacation for the first week, and in Mar, there is another one week vacation for March Break, in Jun, the last week could be no school. That's the reason you always need to register for one year, not month by month
