Lincoln do NOT offer CCC. The standard offers for their 3 year courses range from BBB to BCC. The PP had a son with an UiF who got CCC in the end (which researchers might well link to the UiF, maybe spuriously). The post does say the original offer was somewhere around BB - BCC depending on which one it was.
The lowest offer my DS got which was not UiF was CCD , after an exam . Easily achieved,this was not enough to tempt him becuase - believe it or not- he considered a range of factors (for a Veeeeeery long time!). He doesn't know about the hoodie ( I have only seen this on FB) and won't wear it when he gets it.
I am not sure why the focus on Lincoln bubbles. There is a real range of unis engaging in this ploy. Other than shut down (which is VERY unlikely to happen with Lincoln), I am not sure what you suggest. When I went to Aber on a Visit Day WW3 almost broke out ebtween 2 lectrurers about Unconditionals so the academic community aren't agreed. no doubt, there will be conversations raging in very high places in many unis form the likes of Birmingham, right down to Lougborough College. No doubt they will come up with a new strategy. Who knows why Birmingham is struggling to recruit, with its fine and longstanding reputation, but it clearly is. Nottingham has stopped the practice of UiFs, as has Aberystwyth, but they must have put something in its place. Aber ogffers platinum gym membership to offer accepters and there is a huge range of awards and scholarships, with reduced offers and financial incentives.
According to Which University, the average A Levels on my DS's course at Lincoln are between BBC - CCC. This is actually the same as, for example , Swansea, and higher than some institutions I found.
These unis being mentioned are all more stable than UCFB , for example, which has terrible reviews online , a very low entry rate, high drop out : but is not on the hit list.
