How can these Class 7 Science Revision Notes help you?

Learning theories suggest that how you revise makes a lot of difference in how much you learn and how long you are going to remember the information you have learnt. On the basis of these theories, here are our five suggestions on how to use the Class VII Science revision notes for best results:

  • Organised information helps you learn better: Class 7 revision notes you see here structure the information in the best possible manner. They mention how a topic is related to the other topics you have covered in the past. When you mull over the given information, you understand it better and hence, remember it better.

  • A chapter a day: It has been observed that spacing out your revisions is better than cramming. So, if you have revised a Science chapter today, practice its questions and put down the notes for the day. A 24-hour gap between revisions works best and helps you excel more.

  • Explore the topics on your own: It is true that the Science revision notes we present here for Class 7 students have been prepared by some of the brightest and well-experienced teachers. Still, if you take out time to explore a few things on your own, you will maximise your learning. It might take more time to look up things and find more about them but the process will help you develop the right academic skills you need to succeed later.

  • Write down the answers as expected: The big mistake that many students make during revisions is that they memorise the notes but do not practice enough. Revision notes help you with re-visiting the important concepts a chapter covers while solving questions trains your mind to retrieve them as required.

  • Revise before you go to bed: A 2012 research by Jessica Alber and her team showed that it is best to revise before you sleep or take a nap. The rest makes it easy to remember things for a longer duration of time.
