I have obtained my Free certification codes but there something that bug me the one with the red color.

You can now use the Certification Vouchers to start your exam.

1.The exam vouchers have an expiration date of 180 days after they are received.

2.Once the exam voucher is entered into the VirtualTester client, the test must be taken immediately. So if i entered in the virtual tester the voucher and i don't take the exam within the day does the voucher will expired

Thanks
