Before you sign: ask about the contract, not just the monthly rate. Month-to-month is common; 12-month agreements with cancellation fees are also common and rarely advertised on the wall. Ask what is extra — belt testing fees, uniforms, competition team dues — and whether the head instructor actually teaches the classes you would attend or only the advanced ones.
