Query: Implementation of Course Recommender System for Virtual University of
  Pakistan   Universities working in Pakistan are offering a comprehensive set of degree
programs for different levels. Virtual University of Pakistan is country's
first institution completely based on modern information and communication
technologies. It offers education in many different majors and various areas of
study are available. Multiple courses are offered in each program that satisfy
several general requirements of degree. Selection of courses that align with
competency and interest can become an important factor in determining final
score (CGPA) of student. For this purpose, a web-based course recommender
system specifically designed for courses offered at Virtual University is
developed. User-based collaborative filtering and rating-prediction approach is
used for calculation of expected marks and grades. System is tested against 470
currently available courses and simulated data of 2600 students. Test results
showed that expected marks are somehow dependent on student's average marks in
already studied courses and average marks of similar students in target course.
Accuracy of implemented system is measured using Mean Absolute Error for 100
observations. MAE value came out to be in acceptable range.
