Best tips for getting through Silver 2, 1, and Gold 4?

I've been trying to reach gold for a number of years now and have never done it. I've climbed up to Silver 2 faster than any season previously this year and I feel like my chances are good to finally see Gold. What are some good tips, videos, guides, on these 3 divisions? I'm a Support/Jungle main Main champions are Galio, Morgana, Zac, and Malphite
