The Chinese Proficiency Test (HSK) is China's national standardized test. The certificate has A, B C level. It means you have to take the exam. The test is held two times a year and the next one is on April, I guess. You have to register one month in advance. No exam site in Lesotho and the nearestare University of Stellenbosch and Confucius Institute at Rhodes University in South Afria. Not all university need this. You can go to China to learn Chinese before the university cources.
