in first grade? which? what?
Hi, guys, what is your advice on the following.

1)as for first grade (means year one in school), i have seen two sentences before, "i am in first grade" and "I am in the first grade" which one is correct or natural.

2)as for which and what, i was told that "which" is used when you know all options and choose among them. "what" is used when you do not know what the options are yet. is that correct?
while, the sentence "which bus are you waiting for?" "what subjects do you like most?" "what bus are you waiting for?" "which subjects do you like most?" they all seem fine to me.

Answer

1. Both are OK.

2. The general rule is true, so you've answered your own question ;-) Compare: 
- Which bus are you waiting for? (the A bus or the B bus, I know those are the only two lines that stop here)
- What bus are you waiting for? (I don't know any of the bus lines that stop here)
