MN is certainly an odd place to read about education...sometimes when I read some posters offerings on HE boards I can't believe how bubbled and insulated they are. References to help that schools 'should' offer that are just outside of the experiences of your average child, even at a private school (I recently applied for head of sixth form at my school on a platform of improving aspiration and UCAS support. Got rejected for yet another male yes man. Their loss!). Some MN posters are the opposite of helpful and populate threads with out of date or just ridiculously combative comments ( a lot of tribalism about certain unis). I once started a thread on my older DS and it just descended into a pile on/character assassination of DS with a few usual suspects insisting he should go and work down the pits or something! The names of a handful of unis must set off klaxons in some posters houses or something
.
I have never got the impression anyone regularly on here is like that at all! Everyone is nice 
Sadly, MN has definitely put me off certain universities . However, I am not applying so that's OK! It is also very noticeable that the range of advice is very narrow. So, if someone starts a thread on -say- Aberystwyth vs Hull, with predicted grades of about BBB it takes about three posts before someone says 'they are both distinctly 2nd division and have they thought about the RG/Bristol?' or ' those grades really aren't very good. Is university really right for them?' or 'random irrelevant point about their child who can't bear the thought of a campus'.
DS is possibly focusing most attention on Birmingham (which is very under discussed on MN I find), although he does mention others. He went to an outreach day at Birmingham in year 10 or 11 and got lectured on how they all needed to work harder ( I think other schools had brought underachievers where his school had taken all the nice kids..) and did a tally of the number of times they said Russell Group. However, he knows the campus is nice and that Edgbaston is close. He does also mention other places so I am really hoping there will be some physical open days so he can get a sense of place. Open Days (popular MN belief is DCs should go unaccompanied but -again- your average 17 year old lacks the confidence and wherewithal) and I really enjoyed the mother/son bonding time with DS1 even if he sulked his way round some of them
I think if we stick together during the HE application process it will all go swimmingly. I have recently exited the uni thread (DS is year 2 now) but I had been with the same lovely people since DS was year 10 ( a few of you on here!) and it was always so supportive and kind and a real help to me.
