How to choose the right PhD Course?

Choosing the right PhD Course can be sometimes stressful with so many available choices. Depending on your interest, pick a course/ specialization that interests you. Along with that, try checking its research scope as most of the time, no references are available, making PhD even harder. Along with that, admission requirements for universities should be researched. It is also, however, crucially important to know the possible career options to make it the right degree.
