Saransh, wait till you scientist's start feeding the world, based in max. use of limited rainfall or too much rain. They do say that scientific genetically enhanced food will be a thing of the future, but I find that hard to swallow, let alone imagine. It's not like us hunters will ever become gatherers
Anyway it's no different too the rest of the world when it comes to matric finals... It's all the same pressure and no different to the previous set of exams that you took. How much more effort can you put in if you never gave it your all for the last three years. This one should just be confirmation of the varsity of your choice and the career field thereafter. Enjoy it now... It's the best days ever.....your pressure days are still to come in about 5 years from now.
