Answer 1

I too am getting tired of students posting their homework questions in this forum for a free ride.

If you are not listenig in class or reading and reviewing the material,

then you are not learning the subject matter.

If you do not want to know the subject matter, then why take the class?

Pretty much leaves one conclusion.....You want the credits, but do not want to do the work.

Answer 2

How in the h**l do you consider yourself 'studying' for your big astronomy test tomorrow by coming onto yahoo answers A&S???

This sure the h**l is not 'studying'.

If you want to UNDERSTAND astronomy and not just cheat for the answers to questions you do not seem to understand, try opening up your textbook and READ about the subject.

If you are having trouble reading, talk to your parents and they can get you the help you need.
