Since most engineers are preoccupied with project-based work which would not give
them adequate time to attend regular university classes, there are always online courses they can take anytime. Finishing the course is similar to the processes involved in an online PhD -students have to meet the deadlines and consult with their mentors, but they will be handing in the submission for different subjects through the internet. This breakthrough in information technology by providing online PhD is very beneficial for those who are quite busy with their on-site work.
