**7 Tips to Prepare for Mathematics Olympiad Exams**

- Don’t make reading your pastime: Many people list reading as a hobby on their resumes, and since they have completed their education, they may be right. But since “You” are still in school, reading needs to be your main focus rather than just a pastime. To increase your degree of aptitude, read widely.
- Get Exam Preparation Materials, such as books, dictionaries, mock exams, and Nigerian Mathematics Olympiad Past Questions Pdf. These resources will help you better understand the objectives of the exams you anticipate taking.
- Register for and attend extracurricular classes at your institution. This course will not only help you brush up on your memory, but also showcase your understanding of the material in class and your acquisition of new information.
- Sleep whenever you feel like it: Sleeping is crucial for exam preparation because it aids in memory consolidation. Be careful not to oversleep and only sleep when you feel like it.
- Make sure you are healthy because being sick might make you feel overly exhausted all the time, making it difficult for you to focus on reading. Inform your parent, a nurse, or a doctor if you believe you are not feeling well. Ensure your health.
- Eat when you feel like it: During the exam preparation period, you are advised not to overeat, and to avoid sleep. You need to eat little and light food whenever you feel like eating. Eat more fruits, and drink milk and glucose. This will help you to enhance retention.
- Reduce your time on social media: Some people live their entire life on Facebook, Twitter, WhatsApp, and Messenger chat. This is so bad and catastrophic if you are preparing for exams. Try and reduce your time spent on social media during this time. Maybe after the exams, you can go back and sleep in them.
