But it is through "literature" - ie, your project report - that your technical achievements will be judged!

You will lose marks if your report is bad - even if the work itself is tecnically excellent.

And, when you come to apply for jobs, the first thing the potential employer will see is your ability to write and present a good, clear CV (resume).
You don't get a second chance to make a first impression - if your CV is poor quality, it will not even be read.

The job market at the moment is extremely competitive - you do not want to allow anything to negatively impact your chances!

And, when you have a job, your ability to document your work will be very important - especially if you are writing material for potential customers...
