In writing I am like a lawnmower, difficult and frustrating to start up but once you do the words flow out of me unable to stop like a lawnmower whose blades spin faster and faster and you try to stop it but all your attempts just make it worse and worse and you are desperate at this point and try to stop the blades with a rock but the blades just bend and cause the lawnmower to jump whenever the bump the rock caused hits the ground and you have to let go of it and now it is loose cutting down everything in its path.
So how do you do in exams?
