Thanks @Monkey2001 I will have a look at the HE+ website you mentioned.
Maths is less of a problem actually as we know he totally messed up one paper due to getting the end time wrong (remote exam and he had initially seen the 'extra time' end time by accident) so didn't do it with any hurry then suddenly realised his actual time was up and so had 20 mins less than he thought. Not sure that makes sense but I know what happened! In the paper he did in full he got really good marks. He also likes maths most and therefore works hardest at it.
Chemistry is an issue, school have given very little support. He got an A in the initial settling in report then a C in a test in November ish then got an A in the next one just before Xmas which was a whole term test, thought he knew it so didn't do much for the recent exam and got a C again. Chemistry is also his least favourite out of his subjects (Double maths, Physics & Chemistry)
I feel bad as to be honest he's never really had to work hard before, so I am not sure we have helped him instill good study habits. He has always worked hard in class and done his homework but, if I am honest, not a lot else.
We watched a youtube video from Oxbridge on admissions together earlier and had a good conversation where he agreed he would need to put in the work and he gave the impression that he wanted to do so. We talked about getting a timetable together to plan his work and actually sticking to it, with encouragement from us. He seemed up for it so that may well be tomorrow's task in his free periods.
Problem is DH and I are not the best at sticking to things, so we also need to up our game to help him and give him the scaffolding that he needs to get into a routine.
Sorry for the long rant, I am just getting thoughts out there.
Lucy Parsons does seem interesting, although she seems very full on. I think I may scare DS off altogether if I go straight in there with her methods, so will go gently. How was her study club @orangecinnamon?
