I encourage you to choose wisely . Poor attendance suggests your education may not be a priority and you need to have a conversation with me about this. If your education is not a priority for you then you should not expect that I would want to dedicate my time and effort evaluating your course work and providing you with feedback. It is my opinion that if you miss more than 3 classes then this will not only affect the likelihood of your passing academic courses but it will also affect the dynamics of your learning community. If coming to class is not important to you and you want credit for the course then you are basically taking an independent study.
Independent studies cost additional money.
Therefore, if you have not arranged to take an independent study and you have not paid the additional fees then it would be expected that you would not miss more than 4 classes. Extenuating circumstances such as a severe illness or a death in the immediate family would be given proper consideration. Documentation from a professional would be required. Taking an exam is an opportunity for you to celebrate your knowledge and demonstrate what you are learning. Please keep in mind that tests only reflect a sample of what you understand.
