Hi everybody, this is really urgent and I really appreciate any suggestion. I am applying for the step2Ck exam for the first time. every time I complete all the application steps upto the payment part, when I want to pay it sayas "your session has expired". At first I thought it may be because of the time it takes to fill all the application parts so I went to my OASIS acount- financial summery account to pay from there, but even in my OASIS account when I want to pay it says session expired. What should I do? this is really frustrating. I really appreciate any help. Thank you.
