are you aloud to drink whatever u want in class in high school?

depends what school you go to. My school doesn't allow drinks anywhere but the cafeteria but others allow drinks anywhere in the building.No alcoholic beverages of course..

Obviously no alcohol,

but it depends on your teacher, really.

In some classes I'm allowed to drink coffee, juice, pop, or water.

But others I'm only allowed water. And then there are those teachers who don't permit any drinks in class.

Of course not, assuming your age under 18 (aus) and 21(usa). Laws dont suddenly disapear inside a class room.... wait is this about alcomahole or cordial? Even so if your school says no you could get in the ****.

obviously no alcohol but it depends on the school rules and the teacher it they want drinks and or food in the class. like science for ex. may not want you to have any of that because you cant have it in the labs.

In my school they say no food or drink because of the condition of the classroom but we do it anyway lol We have sodas or drinks from the cafeteria but no alcohol. One kid got caught in my school for having vodka in a water bottle so now we can't have drinks at all

Pretty much. Just no alcohol.
