Which are correct:
[color=blue]1-I get home from work and I have an hour before leaving again for my Spanish class.
[color=indigo]2-I get home from work and I have an hour before leaving again, for my Spanish class.
[color=red]3-I get home from work and I have an hour before leaving again, this time for my Spanish class.
It seems to me that 1 is correct but does not have the meaning it is supposed to have. It implies that the first time too I had left to go to my Spanish class, while in fact I had left to go to work.
Gratefully,
