I have to say that grade wasn’t what I was expecting. I thought I’d done a pretty good job.ProfessorOh, you did. But do you really want to settle for pretty good when you can do something very good?StudentYou think it can be very good? ProfessorAbsolutely!StudentWould that mean you’d…I could get a better grade?ProfessorOh, sorry! It’s not for your grade. It39。s…I think you could learn a lot by revising it.StudentYou mean, rewrite the whole thing? I really swamped. There’re deadlines wherever I turn and… and I don’t really know how much time I could give it.ProfessorWell, it is a busy time, with spring break ing up next week. It’s your call. But I think with all a little extra effort, you could really turn this into a fine essay.StudentNo… yeah…I mean, after I read your ments, I...I can see how it tries to do too much.ProfessorYeah. It’s just too ambitious for the scope of the assignment.StudentSo I should cut out the historical part?ProfessorYes. I would just stick to the topic. Anything unrelated to the use of nature EMITRY has no place in the paper. All that tangential material just distracted from the main argument. StudentYeah, I never know how much to include. You know…where to draw the line?ProfessorTell me about it! All writers struggled without one. But it’s something you can learn. That will bee more clear with practice. But I think if you just cut out the…emm…StudentThe stuff about history, but if I cut out those sections, won’t it be too short?ProfessorWell, better a short wellstructured paper than a long paper that poorly structured and wanders off topic.StudentSo all I have to do is to leave those sections?ProfessorWell, not so fast. After you cut out those sections, you’ll have to go back and revise the rest, to see how it all fits together. And of course, you’ll have to revise the introduction too, to accurately describe what you do in the body of the paper. But that shouldn’t be too difficult. Just remember
