DC is in yr 13. He's aiming for an A in Economics to meet the grade boundary of the most aspirational of his 5 uni choices. He got a high B in his Year 12 mock. He was let down by his answers to the longer questions, including the 25 mark question. Homework feedback from his teacher has been vague - along the lines of "it's fine, but it doesn't feel like level 3". The past paper marking schemes are also more subjective than his other subjects (which are maths, further maths and physics). I've offered to get him an Uplearn subscription, but he thinks it won't be helpful for the longer questions, and he is already confident for the shorter questions. Are there any suggestions of resources that might help?
I suspect the answer may just be "read around the subject" to develop his level of insight and use of economic language. But I live in hope of finding something that might appeal to his more lean and strategic approach to learning. (He's a future engineer at heart, and economics hasn't really inspired him).
