No parent portal unfortunately, Hoghgyni - it's a (very new) sixth form college, and we've had very little contact other than a parents' evening. I'm not sure how much that's down to DS, though - he's not the most proactive at letting us know about things/bringing home newsletters! I'm not aware of any talks/meetings about UCAS at all, even, and DS seems clueless about the whole process. That might be because he missed chunks of the last year due to anxiety, though, so there could have been talks they had that he wasn't aware of.
On the plus side, he said yesterday that he's now feeling better about his results. I had a quick look on Exeter's website for clearing offers (basically because it came up on my Facebook feed because I like their page), and Physics is listed asking BBB, so all hope is not lost, even though typical offers for next year are AAA!
I don't think we're going to make much more progress until he goes back to college at the beginning of September, though. Your DD isn't the only one who's not very motivated at the moment, oneteen (though DS is sleeping rather than partying)!
Maybe I can get him to look at some slightly less aspirational unis in the meantime, though I'm not really sure where is good (but not top-ranking) for Physics. Any suggestions, anyone?
