Easiest way to get Better at the game for Beginners

The only advice I can give is to try to play as many different champions as possible, 3ven if you only play that champion once. Knowing how every champion's kit works has been one of the most crucial factors to my ability to climb. This is my first year playing this game and I was easily able to reach gold 1. Especially as a jungler, knowing if I can gank a lane or win a 1v3 or one shot someone is very helpful in most situations, also knowing if a champion is at a weak point because they just used a super long CD.
