It’s hard for anyone to have no conflicts on the same night for 8 weeks. Life, work, travel, illness, and stuff get in the way and we understand that. We offer these guidelines:
If you are going to miss 1 or 2 classes, we encourage you to register anyways. It’s unlikely you’ll have perfect attendance whenever you take the class.
If you are going to miss 4 or more classes, wait until a class that better fits your schedule is offered.
If you are going to miss 3 classes … well … that’s right on the borderline. If you really think you can make it to all the other five, you might want to register. But then again, one unexpected conflict or illness and you will have to re-take the class. But taking classes again can be fun, so maybe it that bad after all. So if you are going to miss three classes, the choice is up to you.
