Remembering.
Firstly, let the ratios of what people remember, be your guide to what is the best method for you to remember things.
95% what you teach to someone else
80% what you experience personally
70% what you discuss with others
50% you both see and hear
30% of what you see
20% of what you hear
10% of what you read
Don't just be referee with limited knowledge. Be a Referee with unlimited knowledge.
The descriptions above are self-explanatory, so Instead of tackling the 95% end of spectrum let's look at one way of expanding, and getting the best out of the lowest 10% level.
Thirty minutes before each game, read one chapter of the Laws of Associated Football. When officiating in the ensuing game, and when the occasion allows, focus particularly on that Law, and deal with every aspect of that Law as though it was the only Law. After the game, make a list of any problems, and how you dealt with them. Research solutions, and add them alongside your listed items. Add to the list, and as it grows, read it also before each game.
As time goes on, weed out from your list, the learning points that have become embedded into your brain. As the list progresses, start adding non-Law techniques and tips covering man-management, dealing with club officials, fitness, positioning etc.
Finally, to increase your promotion prospects, let us look at the top end of the 'Remembering' spectrum. People remember '95% of what they teach to someone else'.
It is evidently clear that becoming a Referees' Instructor, a Referees' Assessor, or a Referees' Mentor, will hugely increase and improve your performance as a Referee.
