Creating and grading tests is one of the most time-consuming tasks teachers need to deal with. In Vietnam, a startup called Azota wants to help with an online software platform that not only helps educators develop and proctor tests, but also automatically grades them using information from Vietnamese teaching materials. The company announced today it has raised $2.4 million in pre-Series A funding led by GGV Capital, with participation from Nextrans and returning investor Do Ventures. 

Founded last year, Azota now counts 700,000 teachers and 10 million students in primary, secondary and high schools among its users. It says that during peak test periods, it serves over six million users each month, or about 30% of the total number of teachers and students in Vietnam. It claims it can cut down the grading process from two hours when done manually to just two minutes.
