Are there English words used to describe the materials used to cheat in an examination? If yes, please I need some examples.
Yes! Cheat sheet or crib sheet. Found here: https://en.m.wikipedia.org/wiki/Cheat_sheet
A Crib or crib-sheet is defined by the Cambridge online dictionary as
a piece of paper that contains notes or information to help someone remember something, especially one used for cheating during an examination
I believe that this is the term you are looking for
Any other unapproved source would already be called a crib
The cryptanalysts of Bletchley park in WW2 also referred to some of the tools they used to determine the settings used on the Enigma coding machines by the Germans as cribs. This link gives some details of the process.
Normally the examiner says either no prohibited items or unauthorised items.
e.g. Glasgow University example:
Please avoid taking any prohibited items into your examinations. If you are caught with a prohibited item in an exam, – even if you had it with you by accident – it will result in a penalty which could cost you your degree.
e.g. University of Tennessee example :
Do not bring any personal/unauthorized items into the secure testing area. Such items include but are not limited to, outerwear, hats, food, drinks, purses, briefcases, notebooks, notes, pagers, watches, cell phones, recording devices, and photographic equipment. You are not permitted to access any unauthorized items during the exam administration.
When I was in Latin class (50 years ago) a translation that you copied instead of translating the Latin yourself was called a trot. Apparently the word is still in use. OneLook Dictionaries, under “Quick definitions from WordNet,” says this for trot: “noun: a literal translation used in studying a foreign language (often used illicitly).”
