To begin with, you have not been a member of this site long enough to even be considered for Coven leadership. You must have been on this site for at least three months for that to happen.
The Site Administrator is the only one who can grant you leadership of a coven. His decision is made based upon demonstrated knowledge of magic, maturity, contributions to discussions on the board, ability to get along with others, etc.
Pushing to take over a coven when you are brand new to the site is unlikely to gain you what you are looking for and might have negative results.
So far you haven't demonstrated any knowledge regarding magic, various magical traditions, spellwork, or anything else. The fact that you were considered a leader in school is immaterial.
