I need life experienced people advice?
Have you thought of fundraising, that's a fast way. But I would suggest saving up money bit by bit. Do you have a job? It would take time to save the money up for it and you're still young. What's the rush
I don't think you'll get permission, and I don't think this will be a big money maker either. Look for a regular part-time job instead, and save your money for studying abroad. Good luck.
Selling anything at a school is likely to be difficult, or banned entirely. Also check board of health requirements in your country & state/province to see what licensing is required to sell food items. You may need to have your kitchen inspected & meet additional requirements. Probably a really bad idea. Not at a school.
is your dream to make cupcakes? then why are you trying to sell them? If i wanted to go to an art school to learn to make and sell art..i would not support it by selling cupcakes now would i? I would make and sell art
I do not think you will get permission, and you are not going to make much money that way, if you did..
