I've had 3 classes, but was throwing by the second week of the first class. I was the only student who listened to what our teacher said and actually followed his instructions. The other students just thought they could sit down and throw the first day and were sorely disappointed. Most gave up and dropped the class....this happened for three semesters. My teacher is retired now, but I'm allowed to go and do my finish work in his shop. I throw at home though, which is a blessing.
