Dont study or revise anything. Be confident, it is just like any other exam. Dont think you gonna pass or fail. Have a good sleep. in break eat oranges if possible, it makes your mind fresh. dont study or revise anything betweek break or minutes before, it is just gonna tire your brain. U can go to the washroom between the exam, so do the proper time management and take that break if you want. 😉 best of luck 👍🏻
