I mean how could I forget, The simplest and most working technique!
Hereby Social Examination introducing you to The One & Only Awesome trick, THE "Washroom Tech." , Yeah that's right The Washroom Tech. .
For this technique one hardwork is required for the lazy ass ones, you gotta wake up and reach the school early before the exam. All you gotta do is to hide the required notebook in the washroom.
Well when the exam starts, just ask the teacher that you gotta go to the washroom and make a realistic expression.
No one can stop you for that and for a precaution, make a realistic expression from start only. And it gives a bonus if you have a good impression on teacher!
As soon as the teacher allows you , go there and check out everything you have a doubt about but do NOT take too much long!
Have a nice exam. Hope its useful.
