1. Please be clear first. It's not the month you want to save, but the school you apply for requires you to save for several months. It will be clearly stated in the fundraising materials, such as not less than three months. Please look for it. Every school is similar, but individual schools require six months, and even the amount is different.
It depends on the requirements of the school you apply for, and so do other materials. Remember.
Whether you stay or not has nothing to do with your visa. If you save it for 3 months, it will definitely thaw next time you stay, and it won't delay you to remit tuition with this money. Don't read this when you get a visa.
Don't worry about what others do with these materials. There is no uniform standard to deal with the actual situation of the school and your place.
5. If there is no explanation in the information, you need to directly find the school to confirm.
