Start with red,and you have 2 options:
1- after red , go for birds > scuttle crab > blue (my favourite)
2- if you have a better way you can go that way

For gank, if your enemy has cc, wait for level 6. If your enemy dont have CC ask your teammate for a lane freeze.

For drake, if your bot winning lane you can kill drake even in 4. If your bot losing lane, you can kill drake in 8 without help.

For Turrets, if anylane just gave 1 kill go to that lane and kill enemy.Then push lane with your teammate. But if your all lanes winning, wait for a kill and go for turret.

For more xp, i recommend birds or krugs.They will be ez farm for you. And never forget you always need to kill scuttle.I prefer gank mid in 3 and wait for 6. When you're 6 go bot for 2 kills.

In ranked games, be careful to enemy jungler. Play with totems. If you start red , ask bot (or top , changing for side) to totem your blue. Be careful for invade.Dont gank if an enemy so fed, that's just giving him 1 more score. Ask help for drake as soon as possible. You can camp top or bot, easiest way to get kills but you have to wait your laner stop pushing. If your rank is silver or lower, you can mute everyone for a game without flaming.

It's hard to prepare a guide, it takes hours. So vote + will be a great thank for me.
Have a nice day :)
