Student 1 year membership will carry on past my graduation date?

Hi ,

So I am looking to pay for a year of adobe suite for students now to work on my skills before I return to University in September (I am on a placement year and still a student).

So if I buy a year now this will run out March 2019 ... however I will need buy another year after this so that I can have the software until the end of my degree.

What will happen if I pay for another year in March 2019 - as this will take me through to March 2020 , when I will no longer be a student ?
