Remus, yes! One over here! Two years ago, my DS got BCCC at AS, then turned it around to AAA last year! He worked his ass off, and we were all gobsmacked! We were wondering if he should resit the year, but the HoY said that he had seen Bs and Cs turned into As and Bs, which is what DS needed.
We started by getting photocopies of his papers back, to see if a remark would be advisable, sadly not! But, that was really useful, as he sat down with his very helpful teachers, and found out where he went wrong, and where he needed to improve.
Next, we found good private tutors, who were a big help. We asked for friend's recommendations to find these.
Next, DS found the exact exam specifications on the internet, and worked to them.
He was fortunate to have the choice of January resits, so he decided which exams he would resit in Jan, and which in June. Think strategically about these, where she needs the most marks, and where she can pick them up.
Which subjects is your DD doing? DS did chemistry, biology, maths and economics, and dropped economics. Not sure if all this advice is as relevant to essay subjects.
He studied every day, with only Christmas Day off, and did as many past papers as he could find, making a chart of his results for them.
Reading back, it's a wonder that we all survived the year! He needed ABB for his chosen course, and was so desperate to achieve it. He was good friends with the kids going for medicine, and asked them for any study tips.
My longest ever post! But I was so desperate for any encouraging news when I was in this position two years ago. Best of luck to your DD, and you, for a tough year ahead. Please feel free to ask any questions.
