See this question.
- Submitting a transcript which indicates an incomplete study (50/120 credits completed) and 5 dropped (not failed) courses.
See this answer.
Honestly, unless there is some compelling reason ("My father died." "I was in the hospital with a broken back.") as to why you have so many dropped and uncompleted courses, there may not be a way you can just brush away your academic record into omission. There is not a great way to spin doctor this.
If I must complete my study, do I must complete it in the same university and country I started my study in?
The university from which I obtained 50 credits, is expensive and the country which this university is situated in, in hard to get a visa. So, I was thinking to resume my study all over again but in a country where it costs less and doesn't have visa issues.
Would I look good as a Ph.D. applicant if abandon one university program and then pass from another program?
