Thank you Vill and sorry everyone for not making it clear from the first time. That is correct, there is a combat class/lab within the academy's building close to the rest of the classrooms- more like Armina's office and where the written exams are held on basic Grimm knowledge and a second building- the training ground, gym etc where they can also use their weapons without fear of destroying the academy's common rooms etc. I will be more descriptive next time :)
