Punctuation Mistakes in Essay Writing
Although punctuation is of utmost importance for successful writing, using punctuation marks correctly is probably the most neglected writing skill. The most common mistakes in terms of punctuation can be divided into those referring to the use of apostrophe, comma and hyphen:
