Change the subscribe from normal to student plan

To change your standard Creative Cloud subscription into a Student Creative Cloud subscription, I recommend  cancelling your current subscription and taking a student subscription. The super reduced price is available for the first year. You don't need to uninstall/reinstall the software and also elements stored in the cloud will stay, as long as you do not change your Adobe ID (e-mail)! You will most likely need to provide proof of the student status, so keep that ready. Update this thread if you need further help.
