Some common flaws in reports (from other courses)
Using the KTH logotype on your report or presentation is not permitted.
Incomplete references
Missing important citations
Statements made without justification or supporting citations
Poor (or no) editing
Failure to spell check the document
Documents which it is clear that no one looked at after formatting - often these have breaks in the middle of sentences, missing phrases, ... .
Using figures from others without the copyright owner's permission
Lack of page numbers
Unreadable text in figures
Failure to label elements of figures adequately
Use of contractions - you should avoid using contractions in a formal report
Use of acronyms or abbreviations without properly introducing them; often failure to use these acronyms and abbreviations consistently through the rest of the paper
Redundant text
Using too few references, often the paper looks like simply a cut and paste edit of these references.
Single sentence paragraphs
Lack of vertical white space between paragraphs, which in some cases makes it hard to understand where new paragraphs begin
Lack of a date - every document should have a date, in addition to the title and author(s), and most references should have more information - keep in mind that the goal is to enable someone (perhaps even yourself) to find the reference at a later point in time
Sections and subsections are not numbered - hiding both the structure of the document and making cross-references difficult
