The payments to take Spanish classes with your tutor are made in advance, either with credit, debit card or with Pay-Pal. They can also be made in cash, as long as you are paying a full week or a full month in advance. (The payments for individual classes are not accepted) you can also pay the entire week of lessons by credit or debit card when starting the first class. (Personal checks are not accepted)  The best way to pay is after arranging your lessons with the tutor, during the same phone call your tutor will send you a bill to your e-mail address that you can pay immediately. Many students would pay a week in advance; others would pay a month in advance, so you decide whether to pay for the week of classes or you should pay for the full month and ensure your room with your Spanish course. So you can pay week by week or month by month.
