I know some if not most of you would be nervous if you can ace an interview or not. A 10-minutes interview would feel like a 10-hours interview if you keep on getting nervous, or worst if you panicked out. Therefore, I really suggest you to get ready for these 'confrontations' as its probably the most important part of getting a scholarship. Once your application is accepted, they won't judge you by your marks or grades anymore. Its YOU they're gonna judge. So be prepared inside and out! These are some links that I have researched which contains high quality words of knowledge to successfully pull an interview. So, good luck!
