The point of an exam is to see if YOU know the material that you were supposed to have learned. I for one am not going to check your test for you and help you cheat.

Hi, elenaj!

If you could and would show people that are able to help you here because of the knowledge that they have, as to how you arrived at your answers, and why you think they are the correct answers, then experts in accounting would be more likely to help you to figure out how to arrive at the correct answers in order to help you to learn on your own.

Thanks!
