There is a lot of difference between the ActEd solutions and the exam reports. I understand ActEd solutions are designed for distance learning but can I really be as brief as the exam reports are?
Hard to say but generally the caveat on the model sol'n is that that is what a well prepared candidate might produce in the time. So if you believe that, then yes. Remember the golden rule. Bear in mind no. marks available before you over-elaborate. Otherwise you'll run into time pressure. Hope whatever strategy you use works!
