Mark my sentences?

[Dante17]

Hello again

Could someone please mark my sentences? Just wanted to see if they are correct.

1. " I am not free today. (It's) because I have a test tomorrow "

2. " Let's go out tonight, because tomorrow is a holiday."

My answers:

1. Watashi wa kyo hima ja nai. Ashita tesuto ga arimasu kara.

2. Konban dekakemashou. Ashita wa kyujitsu kara desu.

Thank you !

1)
"Ja nai" is not a polite form. You'd better unify the writing forms.

2)
Ashita wa kyūjitsu desu kara.

Kara is put at the end of the sentence in the first example (Ashita tesuto ga arimasu --> Ashita tesuto ga arimasu kara). It's quite the same here.
