Ninja exams: help needed?

Question

Can someone tell me how to the differetn exams work? Like what part or the year they occur and what do they ask of you to do?

Particulary:

- When do you join the ninja academy?

- How may years you have to stay in the academy?

- Which of the 2 chuunin exams was the one Naruto participated in (1st or 2nd of the year)?

- Tell me about the Jounin/Special Jounin/ANBU exams (presuming they exist).

Thanks.

Answer 1

-You can go anytime because Konahomaru (sorry probly spelt wrong) was in the academy after special training, but it is assumed that you can go anytime.

-It only takes one, unless you flunk out a couple times like naruto, I guess

-He participated in the 1st one of the year,  The second one happened while he was training.

-Jounin/S-rank Jounin/ANBU are unknown.  It can be assumed that the Hokage chooses which ninja heads up in the ranks.

Answer 2

- You can start any time because Kakashi went to the academy at age 5 and graduated in a year.

- Like I said Kakashi graduated in a year, so it really depends on the ninja and how skillful they are.

- Naruto participated in the 1st chunin exams with all the other rookie 9.

-I'm not really sure about the Jounin/special jounin/ANBU exams...I don't know if they even exist. I never really heard of it on the show.  

Answer 3

There is one spot in the manga (I don't think the line was in the anime) where the existance of Jonin exams are strongly suggested, but it made it sound like each village handles their own individually and they aren't held (at least in the Leaf) with any regular schedule (more of an as needed basis).
