Well I'm not really sure what it could be. I did take the quiz and the probability that I have ADD/ADHD was high. However, it also said that this doesn't develop in adult hood and I feel like during my childhood/teenage years I wouldn't fit the criteria. I'm pretty sure it's not dyslexia.

Yes, my memory is very bad. But I am clinically depressed which makes it extremely difficult to study because most of the time I am unable to focus and concentrate so things don't sink in. Also, my study skills I think are probably next to nothing and I believe that I have social anxiety since most of the time being on campus or in class was extremely difficult. I don't really know what the problem is, it just feels like I really messed up, but I really did try. I do get stressed out before tests, but i think it's more than just stress. It's more than drawing a blank, a lot of times (sometimes at the beginning of the test or a bit into it) my mind just doesn't register what it reads. I have to read the question over several times before it sinks in. The thing that really frustrated me was that for one of my classes the prof said that he designs his tests in a way that if we attend lecture and do the readings we should get an ok grade. I not only attended lectures and did readings but I studied and I barely passed his tests. I feel like I just can't grasp things. During group work I'm usually completely lost. I receive the same instructions as everyone else does, but I either have no idea what we're suppose to do, or I'm way off. I feel like I might as well be attending a school in a foreign country where the language they teach in is unkown to me. I know that something isn't right, things should be turning out this way, not when I'm trying.
