Find out how the new GCSE grading system will work in England
It's that time of year again, when the school and university students are preparing for their exams.
Students will want to put themselves in the best possible position to get those grades by taking notes, revising and completing practice papers.
But it's not just about hitting the books or getting creative with post-it notes.
What students eat and drink can make a difference too.
So to help you out, we asked University of Sunderland lecturer in exercise physiology, Dr Paul Innerd for his views on the best nutrition to help see young people and students through exam season.
Start with water. Make sure you get enough. You are roughly 70% water, so it's important that you drink it. In fact, the brain is a mass of water, fat and some protein.
Water allows brain functions to take place, such as thinking and memory.
Berries such as blueberries are packed with antioxidants which are great for overall health and alertness. Studies have found that berries are brain boosters and improve brain function, memory and focus. Pop some berries on your cereal to give your health a kick.
Fats are essential for good health and brain power. Fatty fish such as salmon is an excellent source of omega-3 fatty acids, particularly one called DHA (docosahexaenoic acid). DHA forms a major building block of brain development in children.
Make your peanut butter the natural sugar free variety and you'll get the benefits of those essential fats. Nuts also contain protein which is the nutrient responsible for growth and development of the brain and body.
It's ok to enjoy chocolate now and then, and it’s even better to make it the dark kind. Dark chocolate contains magnesium, which helps you relax and causes the body to release of serotonin, a hormone which improves your mood.
