The way of a shinobi
A shinobi is a ninja that is ranked by level of skill your rank incress and decreases. All shinobi started off as an academy student and then went on to the next test of Genin, Chuunin, Jouinin, ANBU, and Kage. As everyone knows there are missing ninjas which will be explained by your jouinin sensi when you graduate.
Lesson 1:Chakra
Chakra is simply stated, the energy you use when doing a jutsu. Basically, to do ninjutsu or genjutsu, you must mix your Chakra(which is bodily energy collected from cells throughout the body) and spirtiual energy(which is gained through experiences). Then by doing the proper hand poses Seals, the jutsu can be activated. Once Chakra is activated, various techs and movements can be used. Without Chakra a Ninja wouldn't be able to do much.
Lesson 2:Chraka types
Normal Chakra
Normal Chakra is the type of Chakra we see during most of the show, it has a light blue colour to it. This Chakra is sort of a LVL.1 Chakra. It can be used for most skills, but you need a lot of it if you want to perform higher level ninjutsu.

Healing Chakra
Healing Chakra is the kind of Chakra medical specialist like Tsunade and Shizune use for healing-purposes. It's a light green Chakra that can heal physical damage on one's body. All we know is that it heals wounds at an accelerated rate, we do not know if every shinobi has, and can mold this type of Chakra. It seems that the user focuses this type of Chakra to their hands, and then touches the injured spot to begin the healing process. It's unkown if this Chakra is actully used for Skills.

Cursed Seal Chakra
This Chakra can only be used when being marked by Orochimaru's Cursed Seal. (Being bitten by Orochimaru, and having survived the 10% survival-chance.) It's a dangerous type of Chakra. And if it's used too much, it will drain the hummanity from a person, and the user becomes a slave to Orochimaru. This Chakra is dark Purple one, and becomes active when the user is out of his regular Chakra. Visible black shapes will appear on the body and the user will be given a tremendous amount of Evil Chakra power.

Chakra Gates Chakra
By opening Chakra gates (releases the body's limits on muscle usage/Chakra flow) your body and muscles will be put on a lot of strain. Altough your attack will be a nearly suicidal attack, you will be able to perform continuous speed and high powered attacks, making this highly devastating to any opponent. This is the Chakra Lee uses to perform his lotus-attacks. Apparantly this is a deadly type of Chakra that is best used by people Advanced (strong) enough in Taijutsu, hopefully being able to bear the heavy strain placed on your whole body. Someone can open up to 8 Chakra gates, some of the user's Chakra will turn green and surround him. By opening more Chakra gates, your granted power will increase. But in most cases the result is immobility of the user, due to torn muscle fibers.

Lesson 3:Chraka training
Tree Climbing
This training includes gathering Chakra into the feet and climbing up a tree. It teaches to control Chakra by bringing out the correct amount of Chakra in the proper area. The amount of Chakra needed to climb a tree is minimal, but it has to be perfect. Kakashi said that the bottom of the foot is the hardest area to gather Chakra. By learning to control Chakra, an individual can master any jutsu if they try.

Water Walking
A more advanced training than tree walking. Like tree walking, a user must gather Chakra into the feet and constantly feed the appropriate amount into the water. The release of Chakra must match the weight of the body and the amount necessary to float. It is more difficult to control Chakra since water is not solid and constantly moving. This training is used to teach an individual how to create a specific amount of Chakra into any part of the user's body.

Leaf Concentration
This training requires a person to concentrate all his/her Chakra onto a leaf which is placed on the forehead. It's an effective way of training concentration. By calming the mind and defining a target, one is able to draw upon their maximum power. Rumor has it that the Leaf sign on the Hidden Leaf forehead protector originates from this training.

Chakra Molding
Molding Chakra can increase the flow of Chakra throughout your body. It helps you do the other 3 trainings well and enables you to access more Chakra when doing jutsu. Molding Chakra can help you gain Chakra to certain part of the body more quickly.

Lesson 4:taijutsu
Taijutsu is hand-to-hand combat. Taijutsu techniques are much faster and complex than other techniques. Taijutsu slowly tires and wears down the opponent. To use Taijutsu to its full effect, you have to train and push your body to its limit. Many people are not willing to do this which is why Taijutsu is the least favored of the 3 main categories. The only person who really dedicated to Taijutsu is Rock Lee, who is unable to perform any Genjutsu or Ninjutsu techniques.

Lesson 5:Ninjutsu
Ninjutsu is the art of making hand seals and kneading chakra to perform a jutsu (technique). When you make the appropriate hand seal, your desired technique comes forth! Performing Ninjutsu techniques require full concentration and if interrupted, it will not work. It only takes a few seconds to successfully execute a Ninjutsu technique. Ninjutsu is probably the most used attack type out of the three main categories.
Lesson 6:Genjutsu
Genjutsu techniques are mostly illusionary techniques. These techniques cause the opponent to hallucinate and make them think that they see things that are not really there. Genjutsu type techniques are great to use when you are trying to escape or confuse the opposition. While your opponent is confused, you can attack without them knowing where you are.

Lesson 7:Kinjutsu
Kinjutsu techniques are techniques illegal and outlawed by the Kages. Kinjutsu techniques are extremely strong and can cause huge damage. If it is mastered by the wrong person; a whole village could be in severe
jeopardy.

Lesson 8:Hijutsu
Hijutsu techniques are special techniques limited to those who either came from a clan or is the only person that can perform it. Bloodline limits are considered Hijutsu techniques and that ends the lessons.

Lesson 9 biggrin oujutsu
Doujutsu - Doujutsu techniques are performed by the eye. It reads Genjutsu, Taijutsu, and Ninjutsu techniques and defeats them. People who perform Doujutsu techniques are usually geniuses. The Sharingan is considered a Doujutsu technique.
