I understand, I guess your friend travelled when the requirements for getting an appointment date is by sending AL and BA confirmation to Embassy....the booking process has been changed since then..you need to figure out if you fall into Cat.A or not, try to read the new appointment policies on the Embassy website.
But please don’t fund ur account yet. If you have any questions feel free to post it and members here will be glad to help you out.
All the best
Please I want to confirm if this CAT A & CAT B stuffs affects undergraduates as well? You know one needs to apply for admission with 100l transcript.
