I'm really bad at reading the case study properly in business which often ends up with me losing marks as I miss out on key details. When I've been revising I've found it's significantly helped if while reading through it, I highlight all the key details in the case study to help me pay better attention to it. I know you mustn't use highlighter on your actual answer but would it be okay to use it on the case study in the actual exam? Thanks : )
