well done Horsemad to your DS and Ryansbeat to your DD.
DD not done EPQ, school offers it in 2nd term of yr12. First routinely to straight A students, then if places left, others considered. She never applied in the end, in some ways wish she had as could have done a performance. And would have made up for lost 4th AS grade.
That said, all her offers were at the lower end of the typical ranges advertised, but she did have tons of other quite impressive stuff in her PS.
Soton was the only Unl we came across that give reduced offers offers for A grade EPQ. A friend of DDs has a BBB offer for History, but she was an Oxbridge candidate. Same DC also has an unconditional for Birmingham, but don't think that's EPQ related.
I Would have thought than an EPQ would be looked more favourably on with a dropped A2 grade on results day, and admissions are considering the bigger picture. So something else to have in a tiebreaker situation. But would have thought stuff like DofE, sport, music etc works well in that situation too. Had a friend a couple of years back (when the AAB cap was still on) that dropped 2 grades at A2 from her offer for a competitive course at an RG UNI. Kept the place, but did have gold DofE and played a sport to County level.
I think where the EPQ also does benefit, is the research element standing them in good stead for start of Uni courses. At a recent meeting at DD2s school, they mentioned introducing a cut down version at KS3 to start them off early on research skills.
