7 Tips to Prepare for Exams

  1. Don’t make reading your hobby: A lot of people put reading as a hobby in their CV, they might be right because they have finished schooling. But “You” are still schooling, so reading should be in top priority and not as a hobby. Read far and wide to enhance your level of aptitude
  2. Get Exams Preparation Materials: These involve textbooks, dictionaries, Past Questions and Answers, mock questions, and others. These materials will enhance your mastering of the scope of the exams you are expecting.
  3. Attend Extramural Classes: Register and attend extramural classes at your location. This class will not only help you refresh your memory but will boast your classroom understanding and discoveries of new knowledge.
  4. Sleep when you feel like: When you are preparing for any exams, sleeping is very important because it helps in the consolidation of memory. Caution: Only sleep when you feel like it and don’t oversleep.
  5. Make sure you are healthy: Sickness can cause excessive feelings of tiredness and fatigue and will not allow you to concentrate on reading. If you are feeling as if you are not well, report to your parent, a nurse or a doctor. Make sure you are well.
  6. Eat when you feel like: During the exam preparation period, you are advised not to overeat, so as to avoid sleep. You need to eat little and light food whenever you feel like eating. Eat more of fruits, drink milk and glucose. This will help you to enhance retention.
  7. Reduce your time in social media: Some people live their entire life on Facebook, Twitter, WhatsApp, Messenger chat. This is so bad and catastrophic if you are preparing for exams. Try and reduce your time spending on social media during this time. Maybe after the exams, you can go back and sleep in it.
