It is not a secret that there are two main types of essays students may face: formal and informal essays. For the majority of students formal essay writing may be more difficult than the informal one. The differences between these two types are not only in the style of writing.
 
Hardly a student will be given a task to write a formal essay on the topic: “How I spent my vacation?” At all events students should know how to write a formal essay.
 
Formal Essay Writing: Its Main Peculiarities

1. First of all, a student should avoid informal words and other linguistic elements which cannot be regarded as formal ones. In order to have a good grade for an essay a student has to consult dictionaries and write in his/her formal essay sophisticated words.
2. Rhetorical questions are also undesirable elements in formal essay writing.
3. A student should know all the rules of formal essay writing in order not to make stylistical mistakes.
4. Moreover, students should avoid the usage of polysemantic and metaphoric words.
5. Before writing a formal essay a student should think over the structure of an essay and the way how he/she will disclose his/her ideas in the work.
6. The justification in the formal essay should be supported by examples.
7. If a student is not sure about the usage of this or that word he/she should consult a dictionary or his/her supervisor.

Formal essay writing is characterized by objectiveness. A student should not invent examples. He/she is obliged to use only facts.
 
The sentences of the formal essay should not be too simple. A student should bear in mind that formal essay writing is the type of scientific work.
