Is it normal that i can't do lot at once??

I am a computer science final year student. I do studies in an institute which is affiliated with a British University. The system in my country is bit different. That is, in UK, the degree is 3 days per week and full time. In here, we learn the whole 3 days stuff within one day! As a result of it, we are in a race. Our lectures do not have time to explain much, sometimes they provide code to us and do self study because they can't cover it up.

I have an Android class on Saturday.

I joined another very good university for business management as well, that is in this year. It is a full time program, covering 3 days per week. I decided to carry this up for the first year of degree and get the advance diploma certificate. By that time my software degree will be over and I can leave.

But, I got bigger issues. As soon as I started going there I felt a HUGE RUSH in my mind. I was like CRAZY!. Business Management university gives lot of homework and projects. In my Software final year, we got 12 small projects (called as ASSESSMENTS) and one big project.
We are creating a software for a multinational company as well. We will be creating software for other companies, as soon as this project is done.

I study J2ME, C++, QT, OpenCV, Android. Within few days C#.Net and F# will be added to this list. And there are lot of things in Java I forgot, which I need to cover up. I don't like to get second to anyone, so I mst do them all.

As soon as i started business studies, I felt rush, mess, crazy and all. So I stopped it.

Bt I was a famous person there. I had friends, TRUE FRIENDS for the first time in my life. I was known as a genius even though I didn't study even a SINGLE note there. I don't know why, may be because of my leadership and presentation skills.

I stopped this bcs I knw I will fail the exam, bcs I dnt have time to study that, and I must maintain my STAMINA in software studies. We have 2 people with 10 years of software INDUSTRY experience, but I can SIMPLY beat them. Why? Bcs they ask help from me for good software eng. concepts, Good design and for coding! So you can have an idea of who I am, in software field. In other words, I am very good at what I do, still struggling to catch up what I can't.

Bt, I've seen people who do 2 degrees at once (in my case, the subjects are completely different, while in other people's case it is not), job and degree, 3 degrees, and even a girl who did 6 degrees at once!

Bt, why I cnt do like that? Why I mess up everything when I try to do everything at once? I had delayed home work, I hit my head with a tennis racket because of pressure, I was so upset because I can't do enough practice and self studies in software, I had complete 2 months with loads of pressure, I didn't talk to my parents, I was 100% angry, I tried to jump into the road to get hit by a vehicle and die, and much more CRAZY stuff! All of these is because of the fear of "I will not be able to maintain my position in software world, I will not be able to learn the latest technologies (self studies)" like thoughts. And those thoughts are correct.

I hate JUST doing a degree, I need to learn MORE than they teach, using self studies. OpenCV is an example. I am so much attached to this subject. My software lecturers also say to the class "We have one First Class Upper. Who else?".

Now I am 5 days at home doing my homework ON TIME, searching for new knowledge, doing company projects, and learning loads of things (languages and good software concepts stuff) by my self and teaching Java to my software friends ( they also only do the software degree).

Bt I really miss my friends at the business school.

However, there is another thing that you MUST know. That is, my parents didn't send me there to pass the exam. They sent me there to get engaged with the society. We knew I am gonna fail the exam for sure, because I don't study those.

We got 6 subjects there for 1st 6 months. Econ, Math, Business Studies, English, IT and Accounts.. For the 2nd 6 months,2 subjects more.

I tried going there 2 days per week, rather than 3 days.However, there is a 80% attendance law, so it won't work. I can't ask my friends to sign for me all the time, bcs if they caught, it will be a problem for them.

I tried to go there without studying or doing their projects and homework. But it is a dangerous thing to do in there. Lecturers monitor.

Then I tried going there until the first exam, then decide whether I am gonna stay there or not. But,that failed because they sent letters saying we have to do the 2nd installment and complete the payments. I might lose lot of money in that case.

I tried staying without doing homework forever. But we got a new account teacher, she asks students to come to the white board, and she already noticed me 2 times sneaking to others books.

My mother told me 1000 times not to join to this course. She told me I can do 1 thing at a time, and specially, studying lot will drive me crazy so first complete what I am good at. She is correct. I told this whole story to her, she said I need to understand who I am first. Bt she also like that place, I don't know she said that just make my mind good.
Now I am wasting my time thinking about this issue!

Another thing why I gave up.I always want to be thebest in what I am doing. If I feel someone is better than me,I come home, study the weak area, and make sure I am the best again in next week. In this management course, I am going there without studying and without doing their homework; I don't want to be the last one in the class or LOW Ranked student. This happened to me in my school while I was studying for A/L Commerce, I can remember how teachers and BRIGHT students thought I am an Intelligent looking Idiot who is hard to find. I don't want to happen that to me again.

And,all the students in the business class are after A/L people. So teachers treat all of us thinking we are all just after A/L. I hate it! It is really hard to listen to their advises given to us thinking we are all after A/L!

According to me, I want to work FREELY without getting into too much of work at once. That what I understand about my self. But I feel horrible about stopping that course. Even though I got lot of work to do, I feel lazy, because lot of time is spent to think about this stupid thing. Did I disappointed my parents?

Why I can't do lot of things at once as some people do? Am I a dumb idiot? Am I a NON-Talented guy? Crazy moron? Please answer.

PS:
I did A/L's in commerce, and I hate it. I wanted to do Math, but because of a problem in our school's Math section, I thought it is better to go with commerce. However I am the second highest in school, in O/L Math. Final day of school was the happiest day in my life, because I said good bye to commerce studies.

And I am 22. Everyone in my Business class are 1 to 4 years younger than me. I am the second eldest, among 240 students.
