Creative cloud: teacher/student plan

Hello! I'm hoping that this is the right place to ask such questions, and more so that someone will be able to help me with this dilemma. I love using Adobe programs such as InDesign and Photoshop but more than that theyre a vital part of the current class I'm taking. I pay 20 dollars each month (a great deal) in order to access these programs, which isn't the problem. The problem is that I don't need these programs during the summer and winter break. Money is tight for a University student and 60 dollars isn't 5 dollars. I contacted Adobe support and they currently transfered me onto the Adobe free 90 trial. Thats great for my current month of winter break, but in the near future there won't be a second free trial... So here's my question, is there any way in which I'm able to switch on and off (so to speak) during semesters and breaks so that I don't have to pay the cancelation fee each time? Thank you in advance!
