It took me 5 (vs the typical 4) years to finish my undergrad degree. I chose to take a break from college after 2 years because I was struggling so much: I was seriously underperforming academically, due primarily to executive functioning and social difficulties. I received no accommodations because I had no idea I was on the autism spectrum; there was really no name for it back in the late 80's, early 90's.
I quickly decided I needed to get back into school, but I wanted a "fresh start" so I transferred.
Needless to say, I continued to struggle at my second university but did a little better, and managed to graduate with a 3.2 GPA (not stellar, but not bad considering).
Almost 20 years after getting my Bachelor's in Psychology, I earned a Master's in Education with an emphasis in Applied Behavior Analysis. I graduated with a 3.98 GPA, and am now working on my behavior analyst board certification.
Yes, I am "high-functioning" but my difficulties have very effectively wreaked havoc all over my life.
Sometimes, I am amazed I am still alive and in one piece, let alone married with kids, and an advanced degree, though I am underemployed...like most of us.
