Tips to prepare Class 8th National Science Olympiad - NSO
Follow the tips to follow as your last mile preparation and login to create self learning environment
1. Strategize Your Time
Plan the 24 hours what you have. Study for sufficient time. Go through at least three subjects in a day. Apart from studying, set a time aside for your relaxation. Do whatever interests you – listen to instrumental music, draw, paint or watch an infotainment channel for not more than an hour.
2. Write What You Learn
Once you learnt your topic, make it a habit of writing it down. Experts advice that you must try to write it down at a fast pace though it’s sensible if you don’t spoil your handwriting in this practice. This habit of writing a topic will let you analyze how much time you are taking for it. It will ultimately help you to manage your time during your exam.
3. Don’t Ignore Diagrams
When you are tired of reading, sit and draw diagrams. It will help you not only to relax and but also learn the topic as well. You can figure out what you missed while drawing it and rectify it accordingly.
4. Have Proper Sleep
Eat, Sleep, Study and relax – That should be your motto rather than breaking your head over textbooks and notes. When you are free and lying on your bed before sleep, recall what topics you learnt for the day. Ask yourself which lesson needs some more attention so that you can plan your study for the next day.
5. Exercise /Meditate
Physical movements like – walking, running, jumping, skipping, hiking and biking – metabolizes brain and makes it more active. Research states, 20 minutes of walk make a student’s brain more active than a student sitting quietly. Meditation improves concentration power, IQ level, helps to focus better, reduces stress, depression and anxiety. Thus, these habits will keep you physically and physiologically healthy during your preparation and exams.
6. Create Mental Associations
Try to relate what you learnt with different subjects. Making connections is an easy way to remember a lesson. Steve Jobs once said, “Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn’t really do it, they just saw something”.
7. Use Mnemonic Technique
8. Study in a Group
Studying in a group helps you to gather new insights from your fellow mates. This process enhances your learning experience. In a group study, you share resources, interact with members and discuss ideas with your team. This habit will make your learning interactive.
9. Watch a Videos on a Topic with different resources
To learn a subject in a fast and easy way, try to watch a video of the lesson or topic you are studying from School Connect Online. Visuals help to retain things in an easy way.
10. Don’t Stay Up All Night Before Exam
Relax the day before your exam. Revise and go through all relevant topics. Focus on important topics. Have a proper dinner and sleep on time. Before going to bed, get your stationeries, admit card for exam and clothes ready for the next day.
Take practice tests and increase your speed and accuracy from School Connect Online. Manage your time well and complete the syllabus on time.
