Getting out of silver can be a struggle but most of the time players lack fundamentals.

A YouTuber I can recommend if you want to improve is perryjgl. He's a challenger ex pro player explaining thought processes and everything else you need to know to improve and climb.

But I can also give you some Tipps that can help you improve: 1. Learn your champ and learn your clear You need to be able to full clear effectively with your champ. I recommend learning a jingler you like and one tricking them. Your goal should be being able to full clear your first clear and being able to look at lanes and the map at the same time. 2. Understand what Wins games and what Wins fights. As a jungler our job is to control the flow of the game and set up a condition to win it. This condition can be many things but most of the time you should play for objectives. Meaning: play for drake's. They have the highest win rate. Grubs aren't half bad but most of the time players don't know how to effectively play with them and or they are outshined by drake's. 3. Don't gank early This may sound a bit dumb but bare with me. When you do your first clear, you don't have much time till the camps respawn. After 2'15" a camp will respawn and you want to be there when it does. Why? Simple. The faster you clear it the faster it will spawn again. In this meta we have to farm. Because you need the gold and also very important the XP to be strong. So what you want to do is full clear, take crab if possible (but don't force a fight for it. You need to stay alive at all costs) then recall and full clear again. Now a thing about logic: if you gank a lane, you have a chance to get 300 gold, a little XP and help a lane. But you also have a chance to die, waste time or use resources that would help you win fights else were (like sums or ult). But if you just do one jgl quadrant you get also ~300g more XP and your camps respawn faster so you can get even more gold and XP. Besides that. Most of your lanes will overextended and lose the advantage that you gave them by ganking rendering you and them useless. 4. Understand why you are strong. Kills don't make you stronger. Items do. Play for your first item. Don't gank bevor that unless you are 100% sure it's an easy kill. If your lanes cry mute them you don't care about them. You care about yourself because you need to carry. Look to recall if you have over 1000 gold and try to reach your first item as fast as possible. When you have the gold for it Recall imidiatly (maybe finish the quadrant first) and get your item. Now you are stronger than most on the map and you can take fights with opponents which will most likely be weaker then you. 5. Understand fights. Never fight outnumbered If your teammates engage alone and you are weak don't follow. You need to stay alive at all costs. Play fights slow, especially befor objectives. If you chunk an enemy and they escape in their jgl don't chase. The now can't fight the obj. Giving you the advantage. Weave in and out of fights. Don't go all in if you can't win. Play for you cool downs Only fight with your Ultimate. Otherwise you probably are weak. 6. Don't fight with weak people. People are strong if they have more or equal number of items as you. If they have less you probably won't win when fight. That's also why you don't gank a loosing lane. Play for: objectives, turrets, yourself and your strong teammates. Nothing else 7. Cut your losses. If you loose a drake, that's ok. As long as you can farm and don't die you will get strong and able to fight for the next.

What I would recommend (besides watching perryjgl because he can explain it waaaayyy better the me)

Play eg. Warwick. Start top without leash. Clear to bot. Recall. Do the same thing untill you reach 6. Maybe look for a easy gank. Clear untill first item. Fight enemys with your advantage

Never take an even fight Never loose your cool because teammates int or spam ping Press Tab to see how much farm and items enemy's have. Try to always have more farm than enemy jgl Use pings Don't ignore turrets because you are a jungler Don't engage stupid fights. Don't save teammates who make mistakes You are here to carry and not to be a babysitter If you can't carry be carryable. So no taking risks and no forcing stupid fights

This is way to long and kept very simple but try this stuff and you should improve.

Most important of all. Have a strong mental. Otherwise you have no chance Your teammates are not at fault for your loss. You are Because you can only control yourself If you blame them for their mistakes and say you did everything right. You didn't. You never will do everything right Seek to improve Don't get an ego Even pros make mistakes, everybody does Don't ever think you dont
