Hello! There are many methods on leveling up. Some people try to sell these methods for real money. I would not advise buying these books because most of them just contain the same old reused information. I am going to list some good leveling methods. Just think of it as your own personal Runescape Leveling Guide. Enjoy.

Let's start with one of my Favorite skills, cooking!
I prefer to fish lobsters at Catherby and cook them, then bank them at the near by bank. But, if you are not interested in fishing, I suggest getting level 60 cooking by cooking anything you can get your hands on, then buy as many lobsters as it takes to get to level 99. Of course this takes money, and if you are short on cash then you will want to fish your own.

While we are on the topic, let me tell you about fishing. As I told you, I prefer fishing at
Catherby, You can easily fish at the shore, than when you get a full inventory go bank them.
If you are looking to make money, do not cook the fish. However, if you want to level both the fishing AND the cooking, there is a house right next to the bank where you can cook them. I suggest keeping at least 2 banks slots open, one for cooked and one for burnt. Then when you are done fishing you can just withdraw the burnt fish as a note and you wont have to mess with dropping each one individually.

Mining Leveling
The fastest way to level up your mining is with Iron. It is fast and it gives good experience. The faster the better in the world of leveling. This is true because if you can mine, say, 20 of one rock, while it takes you the same amount of time to mine another. So less experience points and less mining time is better than more mining time and more experience.

Woodcutting
People tell me to power cut Normal Trees until you reach level 30, then you cut Oak Trees. After you can cut Willow Trees, start cutting. The best place to cut Willow Trees is in Draynor Village. You can cut those until level 99.
