Sorry for the double post and all, but I need some help. I'm having a lot of trouble distinguishing between the particles は、も、and が.
I understand how to use wa, such as in this context:
私は学生。
Except I don't understand how that would differ from:
私が学生。
も I'm pretty good with. Can it only be used for including another topic, though、or are there other uses for it?
