In these days, most of us do copy paste to reduce time instead of typing it manually. Holding Control+A Control+C then Control+V might be easy but you need to know When Copying is become Illegal ? Copying is right when you include below your paper or worksheet who wrote the article or idea and where you get that article or idea you copied. Copying requires permission before copying it. Based on my research, Derivative Work or article or idea you revised by changing of words is also considered a copying. Most of schools are against of plagiarism that's why they are strict in scanning projects and paper works. So If you attempted to copy in the internet, in google or in another search engines, also credit where you get it from or who wrote it just to make sure that your procedures you do in copying are legal and right.
