These are the supplies i used in school. Some of the school supplies are used for note taking and some of them are used for classes and taking exams in school. I started using scientific calculator when I am in high school and I also use it for college.
Hope this shorts will help you get an idea of what school supplies to get for high school and college. These are just some of the stationery i use when i was studying. You don't have to get every school supply i have. Just buy whatever stationery that you really need
