READ the Entire Question paper without thinking what you know and what you don’t
It is extremely important to remember the above point ie reading without thinking what you know. Reading neutrally will take the question (input) to back memory (Hard disk) of your mind and the answer (output) will come when you are ready to take up your first practical question.
Start with a theory question. It takes a bit of time and a relaxed state of mind to retrieve info that is there and needed to solve the practical question. Theory question don’t need much application of mind and there is no fear of being right or wrong.
