Remember that there are very strict rules about using other peoples material. To stay out of trouble ALWAYS reference the source of your diagram/code example/quotation. The University policy is in your student handbook.
Also you should ensure that your references are correctly structured. There are a number of different styles but 'Harvard' style referencing is common in the sciences (including computing & engineering). I know that there are many sites that provide a guide to reference styles but one of my favourites is the Monash University Virtual Library guide to citations.
The Bolland Library also has a very useful guide here. It covers both citing in the body of your text and in the bibliographic referencing. Also it loads faster than a page from an Australian University.
There's nothing worse than a misplace'd apostrophe, see here, suprise your second reader and get them right/rite/write/wright* (downed rust spelt chequers either)(*delete as appropriate.)
Squeeze the last few marks out of your project write-up, check the meaning and (mis)use of awkward words. Won useful sight!
The number of words, the amount of sand, the quantity of work...or is it the quantity of words, the number of sand, the amount of work...the amount of words.... get it right by checking it here.
Have a look at the generic marking guidelines and ask yourself if your work meets these criteria. Be honest with yourself. ps. you'll need Open Office or the Sun Microsystems odt plugin for Word.
