English Requirement for Tier 2 General Application- URGENT!!

Hi all,
My wife has booked an appointment to apply Tier 2 General visa this Friday (20th January 2017) at Hyderabad.
I have a query about the English Requirement criteria, as this carries 10 points.
She has passed Academic IELTS with 7.5 bands overall and not less than 7 band in each module on 30th May 2015 from Glasgow, UK.
CEFR Level is C1.
As per UKVI guidelines the IELTS certificate should be CEFR Level B1 or above.
Can someone clarify if the current certificate with the above details should suffice or does she needs to reappear UKVI IELTS?
Please reply as this very urgent and based on this reply she needs to reschedule the appointment.
Much appreciate!
Thank you.

C1 is a higher level than B1.

Hello dear,

Thank you for the reply.

Please can you advise if you think this IELTS certificate should suffice her to claim 10 points?
