Examinations for multiple courses are held in the same hall. Each course may or may not need a Formula and Tables (FAT) book to be supplied to the student at the beginning of the exam. If a student is issued a FAT book, it should be collected back before he/she leaves the examination hall.

Most students remember to return the FAT book along with the answer script and the invigilator then usually keeps the FAT book in one stack and the answer scripts in separate stacks (one per course)..
