One-on-one tutoring can find out your math problems faster, and teachers can solve them more pertinently. Moreover, one-on-one tutoring, the teacher only pays attention to one student, and the students must concentrate in class and not be absent-minded, so the tutoring efficiency will be higher.
I was in a math tutorial class in the whole high school. At first, it was a small class, but after a while, the grades remained unchanged. Later, my mother signed me up for a one-on-one math tutoring course in high school. In class, my tutor helped me finish one problem after another, helped me to check for missing parts, and then smashed those knowledge points one by one, including many problem-solving skills, which helped me improve my math scores invisibly, and the effect of tutoring was immediate.
