Sync all your students to your account on RDStation, the key advantages are:
Every time you add or update a student, EducationLink tells RDStation, which will save or update the student info.
Log in to your EducationLink account (to learn how to login, access How to login into EducationLink?), and go to your "Organization settings": hover the mouse over your picture and then click in the first link "Organization settings", then click in "Add-ons", find the RDStation add-on and click in "Activate".
Just use EduLink normally, all the sync will happen automatically.
