i am interested in studying in a different country, i have an academic degree already would i have to get a highschool diploma in the country i wish to study in or could i just apply directly?
No, you would not have to get a high school diploma. You have to take some sort of test in order to be eligible for the University/College you would like to attend. SAT type of test, various language tests etc.
You'll be an international student and you have to consult with the head of the university of why you want to go
If you are an alumni of a college, I might suggest talking to that college and seeing if they could offer you a "study abroad" sort of program? Just a thought/suggestion.
As roary mentioned, don't just go straight into it. A lot needs to be thought about such as economic and social factors. I have a friend to went to Grenada to study medicine but within a few weeks he found it an uncomfortable environment.
If you are looking to study in the US, most people have to take the TOEFL exam depending on how good you are at english. If its good, then the next step is the SAT and applying for college admissions. I'd recommend browsing online at state schools first and maybe emailing them to get an idea rather than taking ideas from us as they would be able to give you more definitive answers.
Yep, but in the end I would still have to travel to this country and take the exams there because im not able to take any here, i have like 40 different colleges on the list ( doesnt really matter to me which one i get into )
