NEW YORK, November 4 /PRNewswire/ -- International students now have an online tool that can quickly and accurately convert their non-US grades and calculate their grade point average (GPA) on a 4.0 scale, the WES iGPA Calculator. More and more, higher education institutions are asking for students to give a self-reported GPA on their applications, to enable them to quickly determine eligibility. For American-educated students this is an easy task, but for internationally-educated students who are not used to the 4.0 scale it causes confusion and undue stress. That's why World Education Services (WES) decided to offer this new tool.
