Is a GPA of 3+/ 3.3+ but below 3.5 considered good for scholarships in Europe and the U.S?
In the US it is probably sufficient for admission, but admission to graduate programs here depends on much more than just GPA. Some depends a bit on which courses you got full marks and which not. But even more will be the statements made in letters of recommendation, research you might have (not essential, but helpful), standardized exams (some places) and your Statement of Purpose.
Admissions are handled by people who want to be able to predict your future success. If the many pieces of an application point to that then you have a chance for admission.
However, the more competitive an institution is, the harder it is to &quot;measure up&quot;. So applying to a wide range of graduate institutions is advised if you want to maximize your chances.
Getting a scholarship, however, is a much more difficult proposition. There are few of them (in the US) and may depend on the grant funding of the faculty. Most support for grad students goes to doctoral candidates. But it is possible, here, to apply for a doctoral position with only a bachelors, so you might consider that. It would likely come with support.
