Just entered official website, Purdue University, West Lafayette, inquire. Transfer students must meet the requirements of university credits 1-2 years, and at the same time, they can provide a complete curriculum certificate of high school.
Purdue University has different GPA requirements for transfer students according to different majors.
Agricultural College: 2.5 million
College of Education: 2.8 million (including 3 million for social studies education)
School of Engineering: 3 million
Faculty of Arts: 2.2 million
School of Management: 3.0 minutes
However, official website listed the minimum GPA requirements they could accept. It doesn't mean that your GPA of 2.5, 2.8 and 3.0 will definitely be accepted by the school, because the school will select the best applicants. If other students' GPA is better than yours under other conditions, the school will definitely admit students with higher GPA. Of course, if your GPA is not competitive, you can look for bright spots in other aspects of yourself, such as documents and research background.
Judging from the application experience over the years, the GPA of transfer students should be at least above 3.2.
Wish you success!
