May I suggest Simplilearn issued Exam Vouchers upon the purchasing a course since the exam voucher are valid for 1 year instead of when course taker are ready to take the exam vouchers. From the exam voucher that are being issued, it stated it is valid for 1 year . This will release the frustrations of contacting Support. Or Set up additional menu for those test taker who want to take the exam so that they could sign up for. then it will inform the exam team to work on the necessary or it is set up automatically .
