Im shocked i must admit i thort you were so much older jr1 .. oh well hehe
first question are you sure you want to do alevels ??because .. depending on what you want to do .. say if you wanted to do fashion etc. some art courses etc. may be better and more usefull.. i learned this the hard way
Ok so if you want to leave school you can go to a college.. there are two types of college... comunity colleges which offer a wide range of academic and vocational subjects to any one normally about 14 plus ( all the school drop outs need to go somewere) or there are sixth form colleges which is just people 16 to 19 .. which is good as its more people your own age .. i go to a sixth form college and tbh its not all that disimular to school but slightly mroe relaxed.. ie. no clothing apperance rules.. you could have a tattoo on your forhead if you wanted with bright pink hair (people do hehe) and you can go home in free periods etc. calling teachers by first names.
I would ask my self some questions .. how self disiplined are you ??
colelges .. are so laid back you really need to force yourself to work and want to work (hense why im doing so bad hehe) you dont get as much help really.. its a more mature, relaxed laid back environment then school.
ok this is a retorical question i dont exspect you to answer this but its a factor to consider if its you .. i have add, dyslexia and dyspraxia. and i find that the college has better learning suport if you want it... but school the teachers were more hands on helping etc. so its a different environment. So if you do have any learning difficulties etc. this si something to sonsider.
Also schools i think tend to get better results as they are more disiplined etc. not always but all my friends who stayed on at schools got better results.
But i find that colleges ahve betetr provisions for arts etc. as they generaly have mroe room.
I think in the end it comes down to personal opinion, go to have a look around see what you think, at the end of the day college is a major step for some and a minor step for others its down to you really

I mean for myself, i went from a privaite all girls day school its only 800 people from 2 - 18 were as in sixth form college there is 300 people from 16-18. I found i met loads more different people from all different backgrounds etc. so i really opened my eyes.. were as in school id only ever come into contact with a certain type of person.
Also alot of people in college totally go off the rails abusing the freedom so this is something to consider is this you ??
Sorry to go on abit but seriously i dont want you to make the same mistakes as me, making a rushed desision the day i was due to go back :Flower: and most of all good luck, i hoep you find somewere that suits you.
