Q.Am I eligible enough to pursue a PhD?

Ans. Predominantly, one needs to identify what one’s future ambitions. A PhD is foremost a period of research training and intellectual challenge. Does this feel appealing to you? When we talk about eligibility on the other hand, have you cleared your masters? Or are you on the path of clearing it?
Does the subject you study, genuinely interest you? Would you be okay studying it and researching about the same field for a majority of your life? With the questions mentioned, find answers and you’ll know whether you suit a PhD or not.

Q. How long does PhD take to complete?

Ans. There is no definite answer to this as the time taken for PhD varies from course to course.
In the US, you are eligible for PhD even after you have completed your bachelors and sometimes, master’s completion is not necessarily required.
Although it is always a better option to complete your masters prior to PhD so that you have gained access to the in-depth knowledge of your field, but the choice rests in your hands.

Q.What qualifications do I need?

Ans. A Master’s degree, or its international equivalent, is often required for entry onto a PhD and this is generally the case in arts and humanities subjects. In the sciences, however, students can sometimes move directly towards a PhD after their undergraduate degree.
In addition to some postgraduate requirements, you’ll also need to demonstrate good performance during your undergraduate degree. An upper second class bachelor’s degree is usually the minimum entry requirement.
If the PhD you applied for and are going to study is not conducted in your first language, then you’ll have to provide evidence of proficiency through a language test.

Q.Am I allowed to study part-time?

Ans. Absolutely, many students choose to study part-time, particularly when they are earning on their own, so as to work and earn funds for a college in the other half of their time.
It is likely that most of the funded PhD positions will require a full-time commitment but the self- funded ones, without the hold of any sponsorship, can study part-time and work the other half.

Q. What is an MPhil? Please Elaborate.

Ans. Most UK universities require PhD pursuing students to start their studies by registering for the degree of MPhil. The student is usually required to produce a report at the end of the first year and may undertake a more informal internal examination of this material as part of their upgrade procedure. If their work is judged to be of the required standard the student’s registration will transfer to a PhD.
This procedure is less common in US universities. In the US, PhD students directly jump-start to research in PhD, skipping the MPhil procedure altogether.
