No offense, but wouldn't the curiculum differ from school to school? You'll have to ask your school's senior who had taken those courses or the teachers of those courses for the details of the class, not us. >_>"
100%, they'll teach you the hiraganas and the katakanas, since those are like the alphabets of Japanese, and probably some basic grammars and vocabs, enough for you to be able to construct a couple of simple sentences.
I'm not sure whether they'll start giving you kanjis in your first year though (my school didn't. We only started on the kanjis once we get to Japanese 2 course.) Some schools actually get some basic kanjis into the first year course, but I don't know if that'll be the case in your school or not.
So, certainly, if you ask me what level of Japanese you'll be taught with, it'd be the same as the level of English taught to kindergarten kids, or maybe first or second graders, aka basic stuffs since it's the course for beginners.
However, if you ask how good will you be by the end of the year, ask your teacher or your senior, and certainly, ask yourself as well about that. How good you'll become will depend on how far they'll teach you in your first year and most importantly, like any other subjects, how devoted you are into your study. I mean, when I was in my first year, I already start to try to read the shounen manga raws, taking note of all the vocabularies, grammars and certainly the kanjis, asking the teacher to confirm stuffs I don't understand in them, as soon as I pick up all the kanas. In fact, I start translate in my first year of study, but to my native language and with English script to double check and look at how the sentence structures works from Japanese to English. So, I basically got myself bits and pieces of the languages in the same level as what I'll study in my later years (second year, third year or even higher than that). On the other hand, a lot of my friends just don't give much into it, like don't even pay attention in class. So, in the end, they get near to nothing from it.
PS. Chinese may either help you or drag you when it comes to kanjis. Some characters in Japanese differ from its Chinese origin, and some differ even in its meaning, so be aware of those. Just don't get mixed up between them.
