If you are an off-campus training institution (or similar), if the purpose of borrowing a classroom is to give lectures or lectures, it is best to find a student association in the school (either at the school level or at the college level). You can pay them some venue fees, and they can help you borrow the classroom for your own use. Of course, if it is a joint activity with a student association, it is even easier to borrow it.

Another point is that even if the classroom is borrowed, it is best not to engage in over-commercialized activities, otherwise students may be punished. In other words, try to find the combination of business and education. If it is the education and training industry, there is generally no problem.

P.S. If you are a student at school and want to have a short meeting in the classroom or something, you can basically find a classroom without classes.
