New Pattern Of PTU Exam

I am the student of MBA in Punjab Technical University and I want the examination pattern so can you please provide me? Also provide me the syllabus and the previous year question paper of MBA of Punjab Technical University?

I am pursuing B.Tech Mechanical Course from Punjab Technical University (PTU). I have passed 2nd Semester of this Course and recently taken admission in 3rd Semester. I got news from my friend that the exam pattern for 3rd Semester B.Tech course has changed. So can anyone provide new pattern of exam for 3rd Semester B.Tech Mechanical Course of Punjab Technical University (PTU)?
