It sure is possible. And if you want it you definitly should do it. Regardless your level of SA.
For me the hardest part was motivation. I never really wanted to study. It was just the logical follow up after highschool. So in my case there wasn't an intrinsic motivation. I think the fact that you started this thread means that you do have the motivation. Motivation is the key. In my final year i was motivated to finish and it got so much easier for me then.
Also for me it was hard to concentrate during the classes. Often i was distracted by anxious thoughts. But that was manageble, because eventually the actual studying takes place at home.
Working on projects in teams was no problem for me. I feel relatively comfortable in groups of 3/4/5 people. And its actually an easy way to meet some people in your class because youre forced to work together. It's always harder to approach classmates when you dont have to.
I had to do a few presentations and other communicative skills training during my education. That could really stress me, especially before it even took place. But i improved allot and somehow i feel more comfortable now giving a presentation than being in some other social situations. So sometimes you will be forced to come out of your comfortzone but that's important if you want to improve.
If you choose to go for it, i strongly suggest to talk about your situation with school. Often they are very understanding and help you to make it easier. I never did say anything but i know people who did (didn't have SA though, but other problems).
I hope you make the right decision
