I want to know how to get better and get out of bronze, any good tips?

I was on a winning streak in bronze and then all of a sudden I've started to play really badly and have been on a losing, (partially I know cuz im bad) and i actually got demoted from B3 to B4. I never tilt in games or anything but I don't really think that helps if (but still I never tilt, its never gonna help to tilt XD) I main usually jungle, ADC and top but I feel like what I'm doing is not right and I want to learn things like how to properly farm and CS, or other things like when to know when you need to go into a team fight or how to read the situation. Basically I just want to know how to up my game in league (and also get out of bronze :D) {{sticker:slayer-pantheon-thumbs}}
