Tabystar I'm new to this thread but have DS1 studying A Levels and DD1 studying GCSEs.
DS1 would say he couldn't revise. Thankfully he is naturally able do although probably could of done better, still achieved good grades.
I sat with DS1 and physically revised with him. We made prompt cards together, experimented with mindmaps, looked at the specifications for the subject, used revision guides etc.
It was hard work, exhausting and bloody frustrating, but at least I felt something was being done and it was practical support rather than just nagging.
Fast forward to A Levels he is a different person. He has found revision techniques that suit him, he is focused and on track to do very well.
I do genuinely believe he didn't know how or where to start with revision when studying for GCSEs (also lacked maturity).
I'm also a lone parent and work full time. It's hard not having that back up of another adult in the house which is why I found a positive proactive approach worked better.
My DD is very different, not as naturally able but very independent and has revised and worked hard. She has had a mixed response to the exams this week. I just hope she gets what she needs for her post 16 choices.
