As you may have already guessed, (by the shortness of this post) that if you are reading this; I have run out of time and this is an emergency post.
Now, into the post; I love science. I especially love the theory and the practical elements. But, trying to revise science is rather hard. But I have a few key ways to revise this tricky subject.
How to Revise Science
* Write notes in class and revise from those.
* Write flashcards with questions on them.
* Use: https://www.my-gcsescience.com/ as they have really good videos and small tests on each topic. They only go up to GCSE.
*Use: https://www.youtube.com/user/crashcourse they do have other subject there too, but their science videos are particularly useful. They do videos all the way up to A-Level.
