So basically I have choosen engineering because there are opportunities in this technical field. Like when i graduate atleast i can secure a job at this field. Besides I can give goverment exams and other type of competitive exams. Now let's talk about the timing of how often exams happens, There are 5-6 months of gap between every semester exams, but sometimes due to university rules and orders exams can happen between 4-5 months. And I don't like a thing about our university which is Maulana Abul Kalam Azad University of Technology that they don't check exam papers properly and their syllabus are huge no matter if students have less time to prepare for it, they always makes troubles for students. And even sometimes even topper students got failed due to bad copy checking them after if they do.PPR of their papers they get pass marks.
