Ph.D

Hi Shriya,
Your IELTS score is very low. An overall score of 6.5 is required for any PG level course in the world. But IELTS alone is not going to give you admission. And also depending on how good your profile is this current score may be considered. It is true not just for Germany but also the other two countries you mentioned. Germany is a research hub so it should be your first preference. You must have had very good marks in your Masters, publications, papers, projects, etc. For any Ph.D applicant, relevant paperwork is very important. Knowledge of German language is highly suggested. I will advise you to check options in all these countries, write to the universities and the research heads of the department, rigorous follow up is required. Some high-level recommendation letters are also required to get through the network. Talk to people you know for your LOR. For now start checking with the universities.

Hi Shrinkhala,
This is a grey area and I will advise you to contact UGC directly. As per news and updates, if a candidate has registered before 2009 there is no need to take the NET but there is no update on how far this has been implemented. The requirements also depend on your area of research, university recognition in India and so on. You may also contact some universities and create a personal rapport to understand the requirements and flexibility. Unfortunately, nothing much can be advised now. You may go through these which are just proposals.
