Bullshit education system!

Why do we have to read all those subjects that we don't have any kind of interest. What is the benefit of just reading something to be passed in exams. Its nothing but a bull shit. WASTE of time. This education system should be changed. And why is there time limit for studying a particular subject. I liked the subject "data structure", but can't learn it properly for the time factor. The course ended in 3 months and after that no time to study more about that subject. Why??? because i have to learn new subject. Bull shit. I don't think this education system will ever help me learning anything. It will just give me a certificate with bunch of numbers in it. Bull shit..
