Ugrad 20202021 PowerPoint PPT Presentations

The Global Undergraduate Exchange Program – Islamic Republic of Pakistan (Global UGRAD-Pakistan) was launched by the Bureau of instructional and Cultural Affairs (ECA) of the US Department of State. The program in the Islamic Republic of Pakistan is run by the US Educational Foundation in Pakistan (USEFP) and within the US by the International analysis & Exchanges Board (IREX). IELTS and TOEFL are not required for the Global UGRAD Undergraduate Semester Exchange Program 2020 (Fully Funded) in the USA. Within a brief life-span, the world UGRAD has gained huge quality among the Pakistani university-going, students. The primary batch of a hundred fellows of the 2010-11 Global UGRAD-Pakistan came back to the Islamic Republic of Pakistan to complete their undergraduate degrees at Pakistani universities.
