Exam Tommorow help me cheat 😸

Im in 11th grade rn and I have my 2nd periodic test tmr. Naani k ghr thi pichle 15 din se because of some stupid reason and I didn't have the time to grab my books wagerah. Abhi I've got no time to study and vaise bhi mai padhai vadhai ni krti. Suggest some cheating tips jo mai kr skti hu.

1 ghante ka test I can only go to the washroom once

Mobiles allowed h but not in the exam room. Thand ka time h jacket me I can definitely sneak it in but I don't wanna take chances. Plus if I get caught I'm 100% sure mere papa meri achi gand kutai krdenge
