probably on a scale of 1-10, 10 being the most active, i would say 3?

I have yet to see them fight or anything like that although I see them hang out in their groups.

there are groups not gangs.  im ok with them and they dont really cause trouble. 

Some group can give a helping hands for the goodness to the school, not all gangs are bad. But  others just for fun only. So teens be aware of which gangs can lead you to a destruction, don't go with them. 

exactly! if you go with bad groups then you would also be bad so don't go with them it can destruct your future.

there's a saying that birds of the same feather flock together, so it's up to you to choose of which you go with. Use your common sense!

A standard of living in teens life nowadays is through a group where they belong, if they want to go with the socials then he/she be in a social life but if they want to go with the radicals then sooner he/she be come a radical person and so on with the other groups.
