Nothing gives an overnight result, to be more precise, not a constructive one. We all have to begin early with our plans and make sure we have enough time to see those results for what we have worked so far. But there are some food which can give 50-60 % of the result, if we consume it the night before the big day. But you should have the total clear picture of what to eat and what to not because it will really affect your performance. Proteins are the best things to consume before exams. Do keep in mind, not to take unhealthy beverages e.g. caffeinated and carbonated ones. Try to make protein shakes for yourself which will result in better performance and keep your brain active and fully alive during exams. It will not only be good for your brain but for your health too. Therefore protein salads, shakes and diet really helps in a wonderful way.
