Student plan - subscription when 2 month training

Hi Everyone, 

I'm currently following an Adobe training (only for 2 months) and I got an official paper to proof that I'm a student from the institution. However I'm unsure if Adobe will accept it as it's "short term" training. I found no possibility to reach directly adobe to ask them or upload my document to see if it's approved or not. So the only way is for me to subscribe and so pay directly the yearly subscription but I'm wondering how does it work. Will they ask by after my document ? And what happen if it's not approved, will they automatically switch my subscription to the full plan at 59,99 euro / month ?

Thanks in advance for your advice !
