UC said they would support it due to my extenuating circumstances, how do I coordinate this with the faculty & UC?

asking here cause i’ve been waiting on hold for half an hour to speak to faculty :)))

The double degree I'm looking at doing is a part of the Group 1 of Early Offer program, being 70% on IA1, IA2, and IA3 for 3 subjects and 50% for two others.
Does this guarantee me entry regardless of knowing about the offer until externals are complete? Aka, should I worry about my externals being the end of the world if I bomb them.

Thx for anyone who might know a bit about the subject.

Has anyone sat the EGB211 exam in the last few years? Were the exam questions similar to the practice paper I.e same question type or were they slightly different?
