While registering for the GRE exam in the field of Name - i wrote my first name only
And on my identification id in the field of Name/ Given Name - it is My first name + Middle Name

I did not enter the middle name while registering for the exam
And my exam is on Monday which on 9th of Nov
I have emailed the GRE org , and got an automated reply back they will assist in 24 hours

I also completed the identification id verification which needs be completed 48 hours before the exam
It was successful

But will I be able to give the exam or not???
I cannot afford to reschedule my exam or even pay the fees again

Please help
