Yes, SCEA 2 is discontinued.
I was in the same situation as you. I was preparing for SCEA 2 part 1 when it was cancelled, but in my case I already had the voucher. So, I could take part 1 and, as I also had the voucher for part 2, I am already working on the assignment.
If you don't have the vouchers, I think it will not be possible for you to take SCEA 2.
