It is a normal experience to learn mathematics and vomit. Sprint in the third year of high school and study math very hard. I study math every day, practice in class, do papers after class, and do papers by myself at night. The next day in math class, the teacher handed out the paper I made yesterday and told us the wrong questions. We went to change clothes and study again. We soak in the math bar all day and keep studying. Every day our brains.
