I wonder why you did not do a project in your own company!! Unless it's an autonomus institution, the lecturers may not have the record of the pass rate for the past years. As I worked in a University and set my own papers, and marked my students' work, I kept records of the past results. However, the institution may be able to give you that if they keep records. Unlike in the industry (I have worked in both manufacturing and service industries), in academia there are various factors that determine the results (For example, the differences in the intake; setting of exam papers; change of lecturers mid course, etc). Hence, it will not be possible to identify the cause of either decline in the pass rate or an improvement in the pass rate. That's why, I suggested that you take up exercises which have less variables that affect the performance.
