You sound pretty low, you're not enjoying your course, and you're worried about the future. That's a lot to be carrying. However, I feel I must say that not completing your remaining assessments will not resolve your current situation, in fact it is likely to make it worse. So...my advice to you is to find the wherewithall to get those assessments done to the best of your ability so that you can walk away from this access course job done. Do not preoccupy about what will happen in September at this point. Focus on the tasks that need to be done right now is the way to go forward at this point.
