It is really hard - trying to engage someone who is devastated - encouraging them to step up, snap into action, make decisions, fill in forms, make calls, do an interview etc - alongside your own upset and stress for them. Maybe it will be straightforward - an online form with results and a confirmation later.
But that was not our experience 2 years ago.
There was also the situation where he had to make v quick decisions as in the end he had 4 clearing options - all in v different parts of the country and some v different courses to what he had applied for. So in a few hours he was weighing up uni status vs uni location (lifestyle) vs different course - all whilst being gutted and all his mates out celebrating.
Took a lot of calmness on our behalf. All you can do is try to engage in a discussion around contingencies and provide support on the admin and emotional side.
Might be v different pace this year though as unis will wait for appeals.
