I was asked the following question:
Did you get your 2 AS degrees before or after you where Diagnosed?
And I had a very long reply so I am posting it here.

My first semester during the summer of my degree was differcult, even with only two classes. I wasn't diagnosed yet but I did suspect ADHD, for my daughter and son were just diagnosed. Each class was 4 hours long. I couldn't keep still and my attention just couldn't stay on target. I ended up writing 4 chapters of my short stories during the english class and thankfully they fell into proper writing assignments so I didn't get caught without homework.
(I was 31, in case you are curious. I was an adult who's mind was more like a teen, it felt like).
The good new I was a joy in the class. I had to do a oral report on Conjuctions and I started out by singing "Conjuction Juction, what's your function?" (ABC did small educational songs inbetween cartoons in the 80s). And I got an A.

But the other class, a boring math class - College Math (I had taken up to Calculus 4 earlier in life). And after two weeks. I went up to the teacher and asked to test out. I scored a perfect grade so was allowed out of it... thank goodness!

But I was worried about my full semester courses in the fall. I started out ok, but soon the classes that had 2-1/2 hour lectures were just so frustrating.
A friend of mine who had dyslexia told me of the special needs counsilor at my tech school. I went to see her and she set up a psyciatrist to interview and test me. Again they found my genius level in Math and Science but they found learning disabilities as well. Also Due to family history and the fact I talked rapidly and couldn't keep still during the testing (4 hours!!) I was diagnosed ADHD. I went to a Mental Health here in my city and they gave me a counsilor and a psycologist for meds. I was put on Ridalin.

I was able to stay focused much better and my grades went from Bs to As. :)
But I needed more than meds so the school gave me a note taker and guided my teachers to inform me if we are changing tasks in the classroom. One teacher allowed me to walk in back in the classroom, if I was quiet.

I went to college before when I was 18 and I had a very hard time of it. I repeated classes, was put on probation, and so on. My GPA was 2.0.
After I was diagnosed my GPA was 3.85 :)
I really feel the diagnose and the meds improved my education.

I'll toss my two cents in, since I'm in the midst of a similar situation.

First, I am in the middle of being officially diagnosed with AD/HD. The counsellor/psychologist I had a few sessions with, on referral from my doctor, is convinced in any case. Now I have to wait for the next referral, to a psychiatrist this time, to come through. Been waiting 6 weeks, no idea how long it'll take. But I know I have AD/HD, and it's a very recent realisation. I only began to suspect about 8 months ago, so about halfway through my last year in university.

I am currently pulling a 3.45 GPA in a BA with Honours in History. So I'm doing OK. But this last year, I realized that not only was I not working to my full capacity, I couldn't work to my full capacity. Something in my head just wouldn't let me. Hence, my eventual pursuit of the cause that's led me to AD/HD. But that's beside the point; that's what I hope will make things better in the future. I came here to talk about my past.

I'm 27. I returned to college 2 years ago with about a year's worth of credits I could transfer to my new school (fresh start). Considering that's a year's worth of credits from 4 years of full-time university study, you can tell I dropped a whole lot and got generally poor marks before these last couple years. My GPA, my last year before transferring, was somewhere just below 2.0. Which was a big boost up from the 0.82 it had been after my first year. I'd done relatively well in select courses, but I wasn't capable of handling a full course load. I didn't know why. I thought I was lazy. I know now that that wasn't true, but that's not the point.

The point is that AD/HD, undiagnosed, can screw your college studies. It's possible you can be organized enough to get through it without treatment; I've managed the last two years getting decent grades. But it's been a heck of a lot of work and stress. My point is; if you suspect you might have AD/HD, tell your doctor. Get things moving to determine if you do or don't. If you don't, move on and find out if/what any other issues you might have are. If you do, get treatment. Because otherwise, despite your best efforts, if you get blindsided by a few things your first year you might make the same kind of panicky mistakes I made.

And it's no fun looking back on your year and seeing more Fs and Ws than anything else, and wondering what in God's name happened to the Bs and Cs you pulled effortlessly in high school. I'm aiming for graduate school now, so this isn't a statement that it can't be done without treatment. But I honestly don't think I could handle graduate work without something to help me, somehow, and even what I've done so far has been ridiculously hard at times. And it took me a long time to learn the lessons I have. So do yourself a favour; if there's any question, get tested. Better to know you've got it (or not) and move on than have it hold you back and not know why. Or worse, to know why and still do nothing about it.

You made a very good point. Many many Adders are surprised at college for many of us pulled As and Bs without a problem before hand. Oh there might be some warnings of future problems with boring classes and late homework. But then there is College a much less structured environment where our daydreaming or distraction can go haywire. Plus our somewhat lack of social skills can make getting help even harder and make us look even "weirder" than before. (Although, I was concidered cool by many - so its not all bad news.
