Hi, hope everthing is well. If you haven't use your credit, than it will be fine. The most important one for me was Alzeimers disease, which I missed. And this did not effect my hours since I never miss any off my classes. But, either or some nursing homes will provide you free of charge and let you take the classes you missed. Which this is what I will do.You can also choose your facility. Hope this answer your question.
