A. i am interested in buying the teachers/students plan which is available for teachers and students if they provide a valid email address. is the .ac email address a valid email address and will confirm my relation to that organisation?
B. can i discontinue a plan before the supposed end of it?
B - you pay a fee if you cancel early - read the Subscription Terms https://www.adobe.com/misc/subscription_terms.html
A - when I worked at a University and bought CS6 I used my personal email while providing my proof of employment, so I will GUESS that you may still use any email address you want, as long as you provide the required proof
But, since I don't work for Adobe, the requirement may now be different

When you buy an Education subscription, the terms you "click to agree" should be clear about the first/later years
