The revising stage helps to find punctual and grammatical mistakes. Also helps you to add in or take out nessecary items. When revising you can follow a RACES prolouge better than while you are writing. Hope this helps! ;)
Studying in a public place like a station or bus is the worst. And studying in a library or home is the best. studying in a bus or station is worst because there are, at most times, noisy people around. The more unnecessary noise the less focused you are. And studying at home or a library is way better. The library is quiet so you wouldn't have to worry about not concentrating; being at home may be better because the familiar surroundings keep you comfortable.
I'm not sure that I get the question... Maybe if you gave me a little more information about it I could help you?
