There are no real requirements save whatever you are writing with and a book you are going to not read.
Step 1: In Class
The first way to be success without reading is to pay attention in class. I know this may seem silly, but you can actually learn nearly everything you need to know about a book just by listening and pretending to be interested in the in class discussions. If you feel like there is something you haven't yet picked up, goad your teacher into discussing it. This can be done simply by asking the teacher waht THEIR thoguhts on the section was, or stating that you don't really feel like you grip the section.
Step 2: Out of Class.
Step 3: The Improntu Forwarning.
Many times The teacher will give warnings and hints as to what the improntu will be about, and knowing these give you the utmost advantage. This will allow you to focus the gathering of knowledge to a particular topic, thus allowing you to gain the facts you need, without those useless other things that may only confuse the reader.
Step 4: Actual Writing.
Now this is the time you have been preparing for, the moment where you prove to the rest of the class that their reading of the book and wasting hours of their time on something that will be of no help to them in but of few weeks does NOT give them a better chance at writing. The order you should go about writing your essay should be starting at the front, with the title/author/focus (TAF). Then you should move into your thesis statement, which is where you list three points that support your stance, based on the question your teacher assigns.
Step 5: Body
Writing the body should be the easiest part, if you were successful in your gathering of the informant facts. Your body should include three many paragraphs, each based off one of your thesis statement points. A "improntu" improntu writer's ace in the hole for making assumptions or blatant statements in this form of writing is the use of the crediting " Some Critics Say..." then insert your fact or statement, and it has become true, even if you yourself ARE that critic.
Step 6: Conclusion
This has been how to improntu write an improntu, thanks for reading.
