it says 235 euro and last year it was 140 euro so that's not the right one.
235 euro is the special offer price for 12 months of the Student and Teacher plan.
You must have had a very special offer to get any plan for 140 euro.
Our teacher told us we had to buy it this year for 144 euro but I have no idea where to find that. The link above about plans doesn't do it either. No one in our class figured it out. We had to use helpdesk last year as well.
