A great tip to remember when you are revising

We learn:
10 percent of what we read;
20 percent of what we hear;
30 percent of what we both see and hear;
50 percent of what we discussed with others;
80 percent of what we experience personally;
95 percent of what we teach to someone else.
---William Glasser

Top Tip = if with your friends revising discuss the topic itself, in which you can contribute and take others peoples ideas.
