super angry

I have no fucking idea how to do this stupid tax thing my dad ask me to do.

1) I duno if he has filled in his form B.
2) I duno if he still has to fill in form P if there's no longer a partnership between he and mom. -.-
3) I don't understand how come there's a form P when there's no partnership. -.-
4) I don't know when did they have partnership and how come suddenly don't have???
5) I went online they ask me to fill in section D, when I only got up to section C -.-
6) He didn't even give me a single figure/information and expect me to fill in his form???


I'm seriously going crazy lah.
I studied personal tax. not company tax lah.
