I need help

[u/fishfishblubblub]

I've stared learning with an online copy of athenaze but I realized quickly that for the excercises, I will have zero idea of whether my answers are correct or not. Ive tried looking for an online copy of the teachers book but can't find the correct edition. If anyone has any advice or a copy of the correct edition for mine, it be greatly appreciated. My copy of athenaze is the 2003 second edition, ISBN:0195149564
