Sounds to me like you don't have a clear idea what you'd like to do. Take some time off from school, get some work, find some direction, and apply yourself.

Wandering aimlessly through college(s) is a waste of time and money.

Just curious, are you actually aware of how intense/intensive a B.Arch program is, and do you think you're actually prepared academically or study habits-wise? I get the impression that you bounced around majors from Comp Sci to Chem without grasping the work those majors actually involve. I would lean more towards finishing up that BFA/BA Arts as a means to both hone your portfolio pieces, figure out what specifically you like about architecture, and most importantly improve your study habits, and in the meantime taking a intro to arch summer workshop (CDisco, Making + Meaning, InArch, etc). It's going to take you 5 years either way (2 years for the BA Arts + 3 for M.Arch vs. 5 years for B.Arch). Also, a Masters is a first professional degree, so at minimum, all you need is a Bachelors + 1 semes calc and physics.

Architecure is  the Marine Corp - you must devote yourself to it 150% if you half ass it - you will be making the biggest mistake of your life - you hear me?

I agree with Mike Jaffe. Take a little time off to clear your head. The attrition rate of architecture school is high. You just don't graduate cause you thought you would just give it a shot. 

you must go in it to win it - just like the NY Giants did with the SF 49ers's - who just can't fumble the football in sudden death OT(thesis finals)

Sounded a lot like me in my high school and undergrad days -- and a lot of other people I know whgo fared reasonably well.

Don't be so down on yourself dude.  This is America - where we have the privelege to fuck up as many times as we want to and still make something out of our lives!

You got way better HS grades than me - I ended with something pretty laughable but it still got me into my state university that was known for nothing but partying and football.  My parents taught there so I had a strategic advantage of paying nothing for tuition.  I majored in "General Studies" because I had no idea what I wanted to do for a living.  I partied my ass off.  My first semester's GPA was embarrassing.  I then majored in - you guessed it - Computer Science! - worse decision ever (I suck at math) as I also didn't know my ass from an elbow when it came to programming.  I'm also someone who has been good at art my entire life - this tame I wanted to use it to my advantage and use it for the advancement of my career.  I've also always (my entire life) been inspired by the built environment - this led me to architecture.  I finished my undergrad in art.  Finished with an ok-ish GPA 3.3 or something like that.  I applied to grad school.  This got me into a couple good programs (along with a decent folio and laughable at best GRE scores).

Then I went to Arch school!  It was the best decision of my life.  Cruised right through it.  My professors and I got along nicely - loved the small quaint town, this school also had good football.  When I graduated - I got good offers and since then I've been with some awesome firms in DC.  I'm currently at one of them and looking back at it, I would have never predicted I'd ever be in the place/position I'm in now - a project architect working at one of the world's most reputable arch firm working on a project that is being published everywhere.  Hard to believe only a mere decade earlier I was doing keg stands on a wednesday night only to skip my classes the next day - lol!

The point of my example to you is just to tell you that not everyone's path is the same.  there is no black and white - everyone takes a different path in life.

my friend architecture is an entire different animal. we're in the same boat so i don't feel bad telling you the intensity of architecture almost ruined me physically, mentally, and academically in my first year.  i've been trying to work my way back into another architecture school ever since, but im young an i still have something to prove. BUT JUST BE CAREFUL IT CAN GET CRAZY.

"The point of my example to you is just to tell you that not everyone's path is the same.  there is no black and white - everyone takes a different path in life." - THIS IS TRUE DONT BE DISCOURAGED!!

Thanks for all the advice guys! Yeah I have a good idea what is involved and have taken strides in forcing my self to be more disciplined. I took 8am classes over others to make my sleep habits better and have lowered my hours at work to allow more focus to school. Last semester was excellent for me and this one feels like it will be better than that. I have two more years and I feel that will allow me to get where I need to be in order to succeed. :)

You need sometime to think before you spend a lot of money...Would credits from art transfer over to architecture I think now but you should ask your professors about that
