I've spent a lot of time over the last few weeks working with my final year project students and their reports. They've been sending me drafts and I've been adding comments. This year has been great, because most of them have really engaged with the process, coming to regular meetings and responding very well to what I've said. It has been nice to see the drafts improving in quality with each pass.
The actual hand in date is this Thursday, and I'm quite looking forward to seeing the finished results. If you are writing something it is very important that you go through this review phase, and you allow time to do it. I reckon that a properly written report can add ten percent to a project mark so it is worth the effort.
